EM MICROELECTRONIC - MARIN SA EM6153 5V Automotive Regulator with Inhibit Input and Windowed Watchdog Description Features The EM6153 offers a high level of integration by combining voltage regulation, voltage monitoring and software monitoring using a windowed watchdog. A comparator monitors the voltage applied at the V IN input comparing it with an internal voltage reference VREF. The power-on reset function is initialized after VIN reaches VREF and takes the reset output inactive after a delay TPOR depending on external resistance ROSC. The reset output goes active low when the VIN voltage is less than VREF. The RES and EN outputs are guaranteed to be in a correct state for a regulated output voltage as low as 1.2 V. The watchdog function monitors software cycle time and execution. If software clears the watchdog too quickly (incorrect cycle time) or too slowly (incorrect execution) it will cause the system to be reset. For enhanced security, the watchdog must be serviced within an “open” time window. During the remaining time, the watchdog time window is “closed” and a reset will occur should a TCL pulse be received by the watchdog during this “closed” time window. The ratio of the open/closed window is either 33%/67% or 67%/33%. The system ENABLE output prevents critical control functions being activated until software has successfully cleared the watchdog three times. Such a security could be used to prevent motor controls being energized on repeated resets of a faulty system. Low quiescent current 90 A Very low OFF current consumption < 1uA -40°C to +125°C temperature range Highly accurate 5 V, 150 mA guaranteed output (actual maximum current depends on power dissipation) Low dropout voltage, typically 250 mV at 100 mA Unregulated DC input can withstand -42 V reverse battery and +45 V power transients Fully operational for unregulated DC input voltage up to 40 V and regulated output voltage down to 3.5 V No reverse output current Very low temperature coefficient for the regulated output Current limiting Windowed watchdog with an adjustable time windows, guaranteeing a minimum time and a maximum time between software clearing of the watchdog Time base accuracy 8% (at 100ms) Sleep mode function (V55) Adjustable threshold voltage using external resistors Adjustable power on reset (POR) delay using one external resistor Open-drain active-low RESET output Reset output guaranteed for regulated output voltage down to 1.2 V System ENABLE output offers added security Qualified according to AEC-Q100 Green SO-16 Exposed pad package (RoHS compliant) When the microcontroller goes in stand-by mode or stops working, no signal is received on the TCL input and the EM6153 (version 55) goes into a stand-by mode in order to save power (CAN-bus sleep detector). In EM6153, the voltage regulator has a low dropout voltage and a low quiescent current of 75 A. The quiescent current increases only slightly in dropout prolonging battery life. Builtin protection includes a positive transient absorber for up to 45 V (load dump) and the ability to survive an unregulated input voltage of -42 V (reverse battery). The input may be connected to ground or to a reverse voltage without reverse current flowing from the output to the input.

Exposure beyond specified operating conditions may affect device reliability or cause malfunction. Decoupling Methods The input capacitor is necessary to compensate the line influences. A resistor of approx. 1 connected in series with the input capacitor may be used to damp the oscillation of the input capacitor and input inductance. The ESR value of the capacitor plays a major role regarding the efficiency of the decoupling. It is recommended also to connect a ceramic capacitor (100 nF) directly at the IC's pins. In general the user must assure that pulses on the input line have slew rates lower than 1 V/µs. On the output side, the capacitor is necessary for the stability of the regulation circuit. The stability is guaranteed for values of 10 µF or greater. It is Note 1: Note 2: Note 3: Note 4: Note 5: especially important to choose a capacitor with a low ESR value. Tantalum capacitors are recommended. See the notes related to Table 2. Special care must be taken in disturbed environments (automotive, proximity of motors and relays, etc.). Handling Procedures This device has built-in protection against high static voltages or electric fields; however, it is advised that normal precautions be taken as for any other CMOS component. Unless otherwise specified, proper operation can only occur when all terminal voltages are kept within the voltage range. At any time, all inputs must be tied to a defined logic voltage level.

Power dissipation that would require the EM6153 to work above the maximum junction temperature (+125°C) must be avoided. the thermal resistance specified assumes the package is soldered to a PCB.

The threshold voltage at which reset is asserted or released (VRESET) is determined by the external voltage divider between VDD and VSS, as shown on Fig. 8. A part of VDD is compared to the internal voltage reference. To determine the values of the divider, the leakage current at VIN must be taken into account as well as the current consumption of the divider itself. Low resistor values will need more current, but high resistor values will make the reset threshold less accurate at high temperature, due to a possible leakage current at the VIN input. The sum of the two resistors (R1 + R2) should stay below 500 k. The formula is: VRESET = VREF x (1 + R1/R2). about –30°C, so tantalums are recommended for operation below –25°C. The important parameters of the 10 F capacitor are an effective series resistance of lower than 4 and a resonant frequency above 500 kHz. A 10 F capacitor (or greater) and a 100 nF capacitor are required on the OUTPUT to prevent oscillations due to instability. The specification of this 10 F capacitor is as per the 10 F capacitor on the INPUT (see previous paragraph). The EM6153 will remain stable and in regulation with no external load and the dropout voltage is typically constant as the input voltage fall below its minimum level (see Table 2). These features are especially important in CMOS RAM keepalive applications. Power Dissipation Example: choosing R1 = 200 k and R2 = 100 k gives VRESET =4.56 V (typical) for version V53. Care must be taken not to exceed the maximum junction temperature (+125°C). The power dissipation within the EM6153 is given by the formula: At power-up the reset output ( RES ) is held low (see Fig. 5). PTOTAL = (VINPUT – VOUTPUT) IOUTPUT + (VINPUT) ISS When VIN becomes greater than VREF, the RES output is held low for an additional power-on-reset (POR) delay TPOR (defined with the external resistor connected at ROSC pin). The TPOR delay prevents repeated toggling of RES even if VDD voltage drops out and recovers. The TPOR delay allows the microprocessor’s crystal oscillator time to start and stabilize and ensures correct recognition of the reset signal to the microprocessor. The RES output goes active low generating the power-down reset whenever VIN falls below VREF. The sensitivity or reaction time of the internal comparator to the voltage level on VIN is typically 3 s. Timer Programming The on-chip oscillator allows the user to adjust the power-on reset (POR) delay TPOR and the watchdog time TWD by changing the resistor value of the external resistor R OSC connected between the pin ROSC and VSS (see Fig. 8). The closed and open window times (TCW and TOW) as well as the watchdog reset pulse width (TWDR), which are TTCL dependent, will vary accordingly. The watchdog time TWD can be obtained with figures 9 to 11 or with the Excel application EM6151ResCalc.xls available on EM website. TPOR is equal to TWD with the minimum and maximum tolerances increased by 1% (For Version 53, TPOR is one fourth of TWD). Note that the current consumption increases as the frequency increases. Voltage Regulator The EM6153 has a 5 V, 150 mA, low dropout voltage regulator. The low supply current makes the EM6153 particularly suitable for automotive systems which remain continuously powered. The input voltage range is 4 V to 40 V for operation and the input protection includes both reverse battery (42 V below ground) and load dump (positive transients up to 45 V). There is no reverse current flow from the OUTPUT to the INPUT when the INPUT equals VSS. This feature is important for systems which need to implement (with capacitance) a minimum power supply hold-up time in the event of power failure. To achieve good load regulation a 10 F capacitor (or greater) is needed on the INPUT (see Fig. 8). Tantalum or aluminum electrolytic are adequate for the 10 F capacitor; film types will work but are relatively expensive. Many aluminum electrolytic have electrolytes that freeze at Copyright 2015, EM Microelectronic-Marin SA 6153-DS, Version 2.0, 3-Jun-15 The maximum continuous power dissipation at a given temperature can be calculated using the formula: PMAX = ( 125°C – TA) / Rth(j-a) where Rth(j-a) is the thermal resistance from the junction to the ambient and is specified in Table 2. Note that R th(j-a) given in Table 2 assumes that the package is soldered to a PCB (see figure 13). The above formula for maximum power dissipation assumes a constant load (i.e. >100 s). The transient thermal resistance for a single pulse is much lower than the continuous value. CAN-Bus Sleep Mode Detector (version 55) When the microcontroller goes into a standby mode, it implies that it does not send any pulses on the TCL input of the EM6153. After three reset pulse periods (TCW + TOW + TWDR) on the RES output, the circuit switches on an internal resistor of 1 M, and it will have a reset pulse of typically 3 ms every 1 second on the RES output. When a TCL edge (rising or falling) appears on the TCL input or the power supply goes down and up, the circuit switches to the ROSC. Watchdog Timeout Period Description The watchdog timeout period is divided into two periods, a closed window period (TCW) and an open window period (TOW ), see Fig. 4. If no pulse is applied on the TCL input during the open window period TOW, the RES output goes low for a time TWDR. When a pulse is applied on the TCL input, the cycle is restarted with a close window period. For example if TWD = TPOR = 100ms, TCW = 80 ms, TOW = 40ms and TWDR = 2.5ms. When VIN recovers after a drop below VREF, the pad RES is set low for the time TPOR during which any TCL activation is disabled. 8 www.emmicroelectronic.com 420005-A01, 2.0 EM6153 Timer Clearing and RES Action The watchdog circuit monitors the activity of the processor. If the user’s software does not send a pulse to the TCL input within the programmed open window timeout period a short watchdog RES pulse is generated which is equal to TWDR (see Fig. 6). With the open window constraint, new security is added to conventional watchdogs by monitoring both software cycle time and execution. Should software clear the watchdog too quickly (incorrect cycle time) or too slowly (incorrect execution) it will cause the system to be reset. If software is stuck in a loop which includes the routine to clear the watchdog then a conventional watchdog would not make a system reset even though the software is malfunctioning; the circuit would make a system reset because the watchdog would be cleared too quickly. If no TCL signal is applied before the closed and open windows expire, RES will start to generate square waves of period TWDRP = TCW + TOW + TWDR. The watchdog will remain in this state until the next TCL falling edge appears during an open window, or until a fresh power-up sequence. The system enable output, EN , can be used to prevent critical control functions being activated in the event of the system going into this failure mode (see section “Enable- EN Output”). The RES output must be pulled up to VOUTPUT even if the output is not used by the system (see Fig 8). Combined Voltage and Timer Action The combination of voltage and timer actions is illustrated by the sequence of events shown in Fig. 6. On power-up, when the voltage at VIN reaches VREF, the power-on-reset, POR, delay is initialized and holds RES active for the time of the POR delay. A TCL pulse will have no effect until this poweron-reset delay is completed. When the risk exists that TCL temporarily floats, e.g. during TPOR, a pull-up to VOUTPUT is required on that pin. After the POR delay has elapsed, RES goes inactive and the watchdog timer starts acting. If no TCL pulse occurs, RES goes active low for a short time TWDR after each closed and open window period. A TCL pulse coming during the open window clears the watchdog timer. When the TCL pulse occurs too early (during the closed window), RES goes active and a new timeout sequence starts. A voltage drop below the VREF level for longer than typically 3s overrides the timer and immediately forces RES active and EN inactive. Any further TCL pulse has no effect until the next power-up sequence has completed. Enable - EN Output The system enable output, EN , is inactive always when RES is active and remains inactive after a RES pulse until the watchdog is serviced correctly 3 consecutive times (i.e. the TCL pulse must come in the open window). After three consecutive services of the watchdog with TCL during the open window, the EN goes active low. A malfunctioning system would be repeatedly reset by the watchdog. In a conventional system critical motor controls could be energized each time reset goes inactive (time allowed for the system to restart) and in this way the electrical motors driven by the system could function out of control. The circuit prevents the above failure mode by using the EN output to disable the motor controls until software has successfully cleared the watchdog three times (i.e. the system has correctly re-started after a reset condition).
