MAX6457UKD3B+T

The MAX6457UKD3B+T is a high voltage, low current voltage monitor in 5 pin SOT-23 package. This device operates with 4V to 28V supply voltage and has an inbuilt precision band gap reference, low-offset voltage comparator, internal threshold hysteresis, power-good or reset timeout options and high-voltage open-drain output. Two external resistors set the trip threshold voltages. The MAX6457 is a single voltage monitor for undervoltage or overvoltage detection. A logic-based clear input either latches the output for overvoltage applications or allows the device to operate in transparent mode.

• Internal 2.25V ±2.5% reference

• Open drain N-channel output
• Threshold voltage is 1.228V at TA = -40°C to +85°C, VCC ≥ 4V, VIN rising
• Internal threshold hysteresis of 5%
• Two IN to OUT timeout period is 150ms
• Internal undervoltage lockout
• Immune to short voltage transients
