MAX16133LFM+T

MAX16133LFM+T Datasheet

The are low-voltage, ±1% accurate, single, dual, triple, and ge uP supervisors that monitor up to 4 system-supply voltages for undervoltage and overvoltage faults. The feature independent reset outputs, while the MAX16135 features dual reset outputs. For the 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.

Low-Voltage, Precision, Single/Dual/Triple/ Quad-Voltage uP Supervisors The are low-voltage, ±1% accurate, single, dual, triple, and ge uP supervisors that monitor up to 4 system-supply voltages for undervoltage and overvoltage faults. The feature independent reset outputs, while the MAX16135 features dual reset outputs.

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 are fixed-threshold devices. The nominal input voltage for any input is factory programmable from 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 or 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 are available in a small 8-pin SOT23 package and specified over the automotive temperature range of -40°C to +125°C. ●● ADAS ●● Multivoltage ASICs ●● Storage Equipment ●● Servers Benefits and Features ●● High Precision • ±1% Threshold Accuracy Over Temperature ●● Programmable OV Threshold 104% to 111% ●● Programmable UV Threshold 89% to 96% ●● Programmable Input Voltage from 0.5V to 5.0V ●● Low 15µA Supply Current ●● Quad-Input Monitor ●● 23 Programmable Reset Timeout Periods ●● Immune to Short Monitored Supply Transients ●● Guaranteed Correct Logic State Down to VDD = 1V ●● Open-Drain Outputs ●● Small SOT-23 Package ●● -40°C to +125°C Automotive Operating Temperature Range Ordering Information appears at end of data sheet.
