MAX6305–MAX6313 General Description The MAX6305–MAX6313 CMOS microprocessor (µP) supervisory circuits are designed to monitor more than one power supply. Ideal for monitoring both 5V and 3.3V in personal computer systems, these devices assert a system reset if any of the monitored supplies falls outside the programmed threshold. Low supply current (15µA) and a small package suit them for portable applications. The MAX6305–MAX6313 are specifically designed to ignore fast transients on any monitored supply. These devices are available in a SOT23-5 package, have factory-programmed reset thresholds from 2.5V to 5.0V (in 100mV increments), and feature four power-on reset timeout periods.

The MAX6305/ MAX6308/MAX6311 have two adjustable undervoltage reset inputs (RST IN1 and RST IN2). The MAX6306/ MAX6307/MAX6309/MAX6310/MAX6312/MAX6313 monitor VCC through an internal, factory-trimmed voltage divider. The MAX6306/MAX6309/MAX6312 have, in addition, an adjustable undervoltage reset input and a manual-reset input. The internal voltage divider sets the reset threshold as specified in the device part number (Table 1). The MAX6307/MAX6310/ MAX6313 feature an adjustable undervoltage reset input (RST IN) and an adjustable overvoltage reset input (OVRST IN) in addition to the factory-trimmed reset threshold on the VCC monitor. Program the adjustable reset inputs with an external resistor divider (see Adjustable Reset Inputs section). Reset Outputs A µP’s reset input starts the µP in a known state. These µP supervisory circuits assert reset to prevent codeexecution errors during power-up, power-down, or brownout conditions. RESET (MAX6305–MAX6310) and RESET (MAX6311/ MAX6312/MAX6313) are guaranteed to be asserted at a valid logic level for V CC > 1V (see Electrical Characteristics). Once all monitored voltages exceed their programmed reset thresholds, an internal timer keeps reset asserted for the reset timeout period (tRP); after this interval, reset deasserts. If a brownout condition occurs (any or all monitored voltages dip outside their programmed reset threshold), reset asserts (RESET goes high; RESET goes low). Any time any of the monitored voltages dip below their reset threshold, the internal timer resets to zero and reset asserts. The internal timer starts when all of the monitored voltages return above their reset thresholds, and reset remains asserted for a reset timeout period. The MAX6305/MAX6306/MAX6307 feature an active-low, _______________________________________________________________________________________ 5 MAX6305–MAX6313 ______________________________________________________________Pin Description MAX6305–MAX6313 5-Pin, Multiple-Input, Programmable Reset ICs open-drain, N-channel output. The MAX6308/MAX6309/ MAX6310 feature an active-low, complementary output structure that both sinks and sources current, and the MAX6311/MAX6312/MAX6313 have an active-high complementary reset output. The MAX6305/MAX6308/MAX6311 switch from undervoltage lockout operation to normal operation between 1.5V < VCC < 2.5V. Below 1.5V, V CC undervoltagelockout mode asserts RESET. Above 2.5V, VCC normaloperation mode asserts reset if RST IN_ falls below the RST IN_ threshold.

Functional Diagram Manual-Reset Input (MAX6306/MAX6309/MAX6312) Many µP-based products require manual-reset capability, allowing an operator or external logic circuitry to initiate a reset. A logic low on MR asserts reset. Reset remains asserted while MR is low, and for a reset active timeout period (tRP) after MR returns high. This input has an internal 63.5kΩ pull-up resistor, so it can be left open if it is not used. MR can be driven with TTL-logic levels in 5V systems, with CMOS-logic levels in 3V systems, or with opendrain/collector output devices. Connect a normally open momentary switch from MR to GND to create a manualreset function; external debounce circuitry is not required. If MR is driven from long cables or if the device is used in a noisy environment, connecting a 0.1µF capacitor from MR to ground provides additional noise immunity. The MR pin has internal ESD-protection circuitry that may be forward biased under certain conditions, drawing excessive current. For example, assume the circuitry driving MR uses a +5V supply other than VCC. If VCC drops or browns out lower than +4.7V, MR’s absolute maximum rating is violated (-0.3V to (VCC + 0.3V)), and undesirable current flows through the ESD structure from MR to VCC. To avoid this, it is recommended that the supply for the MR pin be the same as the supply monitored by VCC. In this way, the voltage at MR will not exceed VCC. Adjustable Reset Inputs The MAX6305–MAX6313 each have one or more reset inputs (RST IN_ /OVRST IN). These inputs are compared to the internal reference voltage (Figure 1). Connect a resistor voltage divider to RST IN_ such that VRST IN_ falls below VRSTH (1.23V) when the monitored voltage (VIN) falls below the desired reset threshold (VTH) (Figure 2). Calculate the desired reset voltage with the following formula: R1 + R2 x V VTH = ________ RSTH R2 6 _______________________________________________________________________________________ 5-Pin, Multiple-Input, Programmable Reset ICs VCC VCC R1 MAX6305– MAX6313 RST IN_ VTH = R2 ( ) R1 + R2 VRSTH R3 C* GND *ƒC = ( 1 R1 + R2 2π R1 x R2 x C ) VCC MAX6305 MAX6306 RESET MAX6307 RESET GENERATOR GND RESET µP GND *FOR ADDITIONAL NOISE IMMUNITY Figure 2. Increasing Noise Immunity Figure 3. Interfacing to µPs with Bidirectional Reset I/O The ±25nA max input leakage current allows resistors on the order of megohms. Choose the pull-up resistor in the divider to minimize the error due to the input leakage current. The error term in the calculated threshold is simply: ±25nA x R1 Negative-Going VCC Transients In addition to issuing a reset to the µP during power-up, power-down, and brownout conditions, these devices are relatively immune to short-duration, negative-going VCC transients (glitches). The Typical Operating Characteristics show the Maximum Transient Duration vs. VCC Reset Threshold Overdrive, for which reset pulses are not generated. The graph was produced using negative-going pulses, starting at V TH max, and ending below the programmed reset threshold by the magnitude indicated (reset threshold overdrive). The graph shows the maximum pulse width that a negative-going VCC transient may typically have without causing a reset pulse to be issued. As the amplitude of the transient increases (i.e., goes farther below the reset threshold), the maximum allowable pulse width decreases. If you choose R1 to be 1MΩ, the resulting error is ±25 x 10-9 x 1 x 106 = ±25mV. Like the VCC voltage monitors on the MAX6306/MAX6307/ MAX6309/MAX6310/MAX6312/MAX6313, the RST IN_ inputs (when used with a voltage divider) are designed to ignore fast voltage transients. Increase the noise immunity by connecting a capacitor on the order of 0.1µF between RST IN and GND (Figure 2). This creates a single-pole lowpass filter with a corner frequency given by: f = (1/2π) / (R1 + R2)(R1 x R2 x C) For example, if R1 = 1MΩ and R2 = 1.6MΩ, adding a 0.1µF capacitor from RST IN_ to ground results in a lowpass corner frequency of f = 2.59Hz. Note that adding capacitance to RST IN slows the circuit’s overall response time. __________Applications Information Interfacing to µPs with Bidirectional Reset Pins Since the RESET output on the MAX6305/MAX6306/ MAX6307 is open drain, these devices interface easily with µPs that have bidirectional reset pins, such as the Motorola 68HC11. Connecting the µP supervisor’s RESET output directly to the microcontroller’s RESET pin with a single pull-up resistor allows either device to assert reset (Figure 3). RST IN_/OVRST IN are also immune to negative/positivegoing transients (see Typical Operating Characteristics). A 0.1µF bypass capacitor mounted close to the RST IN_, OVRST IN, and/or the VCC pin provides additional transient immunity. Ensuring a Valid RESET/RESET Output Down to VCC = 0V When VCC falls below 1V, push/pull structured RESET/ RESET current sinking (or sourcing) capabilities decrease drastically. High-impedance CMOS-logic inputs connected to RESET can drift to undetermined voltages. This presents no problem in most applications, since most µPs and other circuitry do not operate with VCC below 1V. In those applications where RESET must be valid down to 0V, adding a pull-down resistor between RESET and ground sinks any stray leakage _______________________________________________________________________________________ 7 MAX6305–MAX6313 VIN MAX6305–MAX6313 5-Pin, Multiple-Input, Programmable Reset ICs currents, holding RESET low (Figure 4). The pull-down resistor’s value is not critical; 100kΩ is large enough not to load RESET and small enough to pull RESET to ground. For applications where RESET must be valid to VCC, a 100kΩ pull-up resistor between RESET and VCC will hold RESET high when VCC falls below 1V (Figure 5). Since the MAX6305/MAX6306/MAX6307 have opendrain, active-low outputs, they typically use a pull-up resistor. With these devices and under these conditions (V CC < 1V), RESET will most likely not maintain an active condition, but will drift toward a nonactive level due to the pull-up resistor and the RESET output’s reduction in sinking capability. These devices are not recommended for applications that require a valid RESET output below 1V. VCC MAX6308 MAX6309 MAX6310 VCC GND RESET 100k Figure 4.
