MAX8211ESA+

The MAX8211ESA+ is a microprocessor voltage monitor with programmable voltage detection in 8 pin NSOIC package. This CMOS micropower voltage detector indicates microprocessors (μPs) power failures. It contains a comparator, a 1.5V band gap reference and an open-drain n-channel output driver. Two external resistors are used in conjunction with the internal reference to set the trip voltage to the desired level. A hysteresis output allows the user to apply positive feedback for noise-free output switching. The MAX8211 provides a 7mA current-limited output sink whenever the voltage applied to the threshold pin is less than the 1.5V internal reference. This device is a plug-in replacement for the bipolar ICL8211/ICL8212 in applications where the maximum supply voltage is less than 16.5V. It offers several performance advantages including reduced supply current, a tightly controlled band gap reference and more available current from the hysteresis output.

• Supply voltage range is 1.5V to 16.5V
• Operating temperature range from -40°C to 85°C
• Supply current is 5μA
• Threshold trip voltage range from 1.11V to 1.19V
• Quiescent current is 5μA
• ±40mV threshold accuracy (±3.5%)
• On-board hysteresis output
• µP Voltage Monitoring; Battery-Backup Switching; Low-Battery Detection;
• Overvoltage Detection; Power-Supply Fault Monitoring; Undervoltage Detection
