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 1.0V 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 1.07V. 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.
