MAXIM INTEGRATED / ANALOG DEVICES MAX821PUST Microprocessor Voltage Monitor
The MAX821PUS+T is a microprocessor voltage monitor in a 4-pin SOT-143 package, designed to supervise power supplies in microprocessor and digital systems. It features a pin-selectable power-on reset timeout delay and provides reliable reset functionality. The device asserts a reset signal when the supply voltage drops below a preset threshold and keeps it active for a specified timeout period after the voltage rises above this threshold. It operates over a voltage range of 1.2V to 5.5V and a temperature range of -40°C to +125°C. The reset output is active low with a push-pull configuration, and it consumes low standby current of approximately 2.5µA at 25°C. The reset threshold voltage is typically 4V, with timeout durations configurable to 0.8ms, 32ms, or 160ms depending on the reset pin connection. The MAX821PUS+T is ideal for system monitoring, consumer electronics, and portable device applications, ensuring reliable power-up and power-down sequences.
