MAX16132–MAX16135 Low-Voltage, Precision, Single/Dual/Triple/ Quad-Voltage μP Supervisors General Description The MAX16132–MAX16135 are low-voltage, ±1% accurate, single, dual, triple, and quad-volt­age μP supervisors that monitor up to 4 system-supply voltages for undervoltage and overvoltage faults. The MAX16132–MAX16134 feature independent reset outputs, while the MAX16135 features dual reset outputs. For the MAX16132–MAX16134, a reset output asserts when the voltage at its corresponding input falls outside a factory-trimmed undervoltage and overvoltage window threshold. The reset is maintained for a minimum timeout period after voltage at the input falls within the factory-set window threshold. For the MAX16135, a reset output asserts when either, or both, of the corresponding inputs fall outside the factory-trimmed undervoltage and overvoltage window thresholds. See Selector Guide for available options. These integrated supervisory circuits significantly improve system reliability and reduce size compared to separate ICs or discrete components. The MAX16132–MAX16135 are fixed-threshold devices. The nominal input voltage for any input is factory programmable from 0.5 to 5.0V, providing a wide range of threshold selections. The window threshold levels are factory programmable from ±4% to ±11%, with ±1% resolution and 0.25% or 0.50% hysteresis. The ±1% threshold accuracy over temperature and window threshold monitoring make these devices ideal for automotive ADAS applications. The reset outputs are active-low, open-drain, and are guaranteed to be in the correct reset output logic state when VDD remains greater than 1.0V. All devices are offered with 23 reset timeout periods ranging from 20µs (min) to 1200ms (min). All reset outputs share the same factory-set reset timeout period. The MAX16132–MAX16135 are available in a small 8-pin SOT23 package and specified over the automotive temperature range of -40°C to +125°C.

These devices offer undervoltage and overvoltage window threshold monitoring within ±1% accuracy over temperature. The MAX16132–MAX16135 are immune to short IN_ transients. Each of the internal comparators are factory set to either 0.5% or 0.25% hysteresis with respect to the selected nominal input voltage. Hysteresis provides input immunity to ambient noise without significantly reducing the input threshold accuracy. See the Maximum IN_ Transient Duration vs. Reset Threshold Overdrive graph in the Typical Operating Characteristics section. Input Voltage Reset Outputs Detailed Description The MAX16132–MAX16135 feature factory-programmable input-voltage-level options from 0.5V to 5V. See Table 1 thru Table 4, as well as the Selector Guide for standard voltage options. The selection of nominal input voltage does not set the voltage threshold levels. For the MAX16132– MAX16135, the undervoltage and overvoltage thresholds are determined by the selection of input tolerance.See the Electrical Characteristics table and Input Tolerance/ Hysteresis section for more detail. Input Tolerance/Hysteresis The MAX16132–MAX1635 are designed to offer eight factory-programmable input tolerance levels from ±4% to ±11% in ±1% increments. The input tolerance level sets the undervotlage and overvoltage threshold levels with respect to the selected nominal input voltage. See Table 5 thru Table 8 for hysteresis and tolerance values. The MAX16132–MAX16134 feature independent, activelow, open-drain reset outputs, while the MAX16135 features dual reset outputs. For the MAX16132–MAX16134, when an input voltage falls outside the set window threshold, the corresponding reset outputs asserts. The reset output de-asserts after the reset timeout period when the input voltage falls within the window threshold. See Figure 1 for more detail. The MAX16135 feature dual reset outputs. RESET1 asserts when VIN1 and/or VIN2 falls outside the set window threshold. RESET2 asserts when VIN3 and/or VIN4 falls outside the set window threshold. RESET1 and RESET2 de-assert after the reset timeout period when their corresponding input voltages are within the set window threshold. At power-up, resets stay asserted for the reset timeout period once VDD is above the UVLO. All reset outputs require a pullup resistor to VDD. Figure 1.

This excursion must be added to the calculated undervotlage and overvoltage threshold settings to account for the threshold variation as shown below: VUVTH_EXC = VUVTH (1 ± 1 % ) Unused Inputs The MAX16132–MAX16135 are capable of monitoring inputs for undervoltage and overvoltage events within a very narrow voltage window. Connect any unused IN_ input to its nominal voltage setting. Setting Input Thresholds The MAX16132–MAX16135 reset devices that monitor input within a window-threshold set by the input tolerance selection. Tolerance setting determines the boundary for undervoltage and overvoltage thresholds. The selected nominal input voltage must stay within the window threshold for the MAX16132–MAX16135 not to issue a reset signal. See below for threshold calculation for 2.5V nominal input voltage and ±10% input tolerance: VINNOM = 2.5V TOL = ± 10 % = 2.250V (1 ± 0.01) = 2.250V ± 0.0225V VOVTH_EXC = VOVTH (1 ± 1 % ) = 2.750V (1 ± 0.01) = 2.750V ± 0.0275V Where VUVTH_EXC is the undervoltage threshold variation and VOVTH_EXC is the overvoltage threshold variation. Undervoltage/Overvoltage-Detection Circuit The open-drain outputs of the MAX16132–MAX16135 can be configured to detect an undervoltage/overvoltage condition. Figure 2 shows the MAX1632 reset output deriving the gate of a PFET low to turn on an LED when there is an overvoltage/undervoltage event on IN. VUVTH = VINNOM (1 − 10 % ) = 2.5V (1 − 0.1) = 2.5V − 0.250V = 2.250V VOVTH = VINNOM (1 + 10 % ) = 2.5V (1 + 0.1) = 2.5V + 0.250V = 2.750V Where VINNOM is the selected nominal input voltage, TOL is the input tolerance, VUVTH is undervotlage threshold voltage and VOVTH is the overvoltage threshold voltage.

An undervoltage lockout ensures that the outputs are in the correct states when the UVLO is exceeded. Bypass VDD to ground with a 0.1μF capacitor as close to the device as possible. Additional capacitor improves transient immunity. For fast transients with large voltage excursion, a filter resistor in series with the bypass capacitor is recommended for proper device operation. See Figure 3 below for more detail. MAX16134 “*”: Denotes optional filter resistor in series with the input bypass capacitance. For a transient excursion of 1.71V ≤ VDD ≤ 5.5V a 500Ω is recommended.
