NCV8502 Series Micropower 150 mA LDO Linear Regulators with DELAY, Adjustable RESET, and Monitor FLAG The NCV8502 is a family of precision micropower voltage regulators. Their output current capability is 150 mA. The family has output voltage options for adjustable, 2.5 V, 3.3 V, 5.0 V, 8.0 V, and 10 V. The output voltage is accurate within ±2.0% with a maximum dropout voltage of 0.6 V at 150 mA. Low quiescent current is a feature drawing only 90 mA with a 100 mA load. This part is ideal for any and all battery operated microprocessor equipment. Microprocessor control logic includes an active RESET (with DELAY), and a FLAG monitor which can be used to provide an early warning signal to the microprocessor of a potential impending RESET signal. The use of the FLAG monitor allows the microprocessor to finish any signal processing before the RESET shuts the microprocessor down. The active RESET circuit operates correctly at an output voltage as low as 1.0 V. The RESET function is activated during the power up sequence or during normal operation if the output voltage drops outside the regulation limits. The reset threshold voltage can be decreased by the connection of external resistor divider to RADJ lead. The regulator is protected against reverse battery, short circuit, and thermal overload conditions. The device can withstand load dump transients making it suitable for use in automotive environments. The device has also been optimized for EMC conditions.

During Power Up (once the regulation threshold has been verified). 2. After a reset event has occurred and the device is back in regulation. The DELAY capacitor is discharged when the regulation (RESET threshold) has been violated. This is a latched incident. The capacitor will fully discharge and wait for the device to regulate before going through the delay time event again. VIN RESET Threshold VOUT FLAG/Monitor Function DELAY Threshold (VDT) DELAY RESET An on−chip comparator is provided to perform an early warning to the microprocessor of a possible reset signal. The reset signal typically turns the microprocessor off instantaneously. This can cause unpredictable results with the microprocessor. The signal received from the FLAG pin will allow the microprocessor time to complete its present task before shutting down. This function is performed by a comparator referenced to the bandgap reference. The actual trip point can be programmed externally using a resistor divider to the input monitor (MON) (Figure 14). The typical threshold is 1.20 V on the MON pin. Td Td Figure 12. Reset and Delay Circuit Wave Forms RESET Function A RESET signal (low voltage) is generated as the IC powers up until VOUT is within 6.0% of the regulated output voltage, or when VOUT drops out of regulation,and is lower than 8.0% below the regulated output voltage. Hysteresis is included in the function to minimize oscillations. The RESET output is an open collector NPN transistor, controlled by a low voltage detection circuit. The circuit is functionally independent of the rest of the IC thereby guaranteeing that the RESET signal is valid for VOUT as low as 1.0 V. VBAT MON RRST RESET DELAY I/O FLAG RESET Figure 14. FLAG/Monitor Function Voltage Adjust to mP and System Power VOUT mP COUT RADJ RESET DELAY GND The reset threshold can be made lower by connecting an external resistor divider to the RADJ lead from the VOUT lead, as displayed in Figure 13. This lead is grounded to select the default value of 4.6 V. NCV8502 VCC NCV8502 Adjustable Reset Function RADJ VOUT VIN Figure 15 shows the device setup for a user configurable output voltage. The feedback to the VADJ pin is taken from a voltage divider referenced to the output voltage. The loop is balanced around the Unity Gain threshold (1.28 V typical).

Adjustable RESET DELAY Function The reset delay circuit provides a programmable (by external capacitor) delay on the RESET output lead. The DELAY lead provides source current (typically 2.5 mA) to the external DELAY capacitor during the following proceedings: Figure 15.

Additional Output Current SETTING THE DELAY TIME The delay time is controlled by the Reset Delay Low Voltage, Delay Switching Threshold, and the Delay Charge Current. The delay follows the equation: Adding Capability Figure 16 shows how the adjustable version of parts can be used with an external pass transistor for additional current capability. The setup as shown will provide greater than 1 Amp of output current. tDELAY + ƪCDELAY(Vdt * Reset Delay Low Voltage)ƫ Delay Charge Current Example: Using CDELAY = 33 nF. Assume reset Delay Low Voltage = 0. Use the typical value for Vdt = 1.8 V. Use the typical value for Delay Charge Current = 2.5 mA. FLAG MONITOR Figure 17 shows the FLAG Monitor waveforms as a result of the circuit depicted in Figure 14. As the output voltage falls (VOUT), the Monitor threshold is crossed. This causes the voltage on the FLAG output to go low sending a warning signal to the microprocessor that a RESET signal may occur in a short period of time. TWARNING is the time the microprocessor has to complete the function it is currently working on and get ready for the RESET shutdown signal. tDELAY + ƪ33 nF(1.8 * 0)ƫ 2.5 mA + 23.8 ms STABILITY CONSIDERATIONS The output or compensation capacitor helps determine three main characteristics of a linear regulator: start−up delay, load transient response and loop stability. The capacitor value and type should be based on cost, availability, size and temperature constraints. The value for the output capacitor COUT shown in Figure 18 should work for most applications, however it is not necessarily the optimized solution. VOUT MON FLAG Monitor Ref.

Cu Thickness), Board Material = 0.0625, G−10/R−4 (eq. 2) HEAT SINKS A heat sink effectively increases the surface area of the package to improve the flow of heat away from the IC and into the surrounding air. Each material in the heat flow path between the IC and the outside environment will have a thermal resistance. Like series electrical resistances, these resistances are summed to determine the value of RqJA: IOUT SMART REGULATOR® 80 40 The value of RqJA can then be compared with those in the package section of the data sheet. Those packages with RqJA’s less than the calculated value in equation 2 will keep the die temperature below 150°C. In some cases, none of the packages will be sufficient to dissipate the heat generated by the IC, and an external heatsink will be required.

RqJC appears in the package section of the data sheet. Like RqJA, it too is a function of package type. RqCS and RqSA are functions of the package type, heatsink and the interface between them.
