MAX16161 nanoPower Supply Supervisor

Analog Devices MAX16161 nanoPower Supply Supervisor is an ultra-low current, single-channel supervisory IC with a glitch-free power-up. The MAX16161 monitors the power supply voltage and asserts a reset when the input voltage falls below the reset threshold. After the monitoring voltage rises above the factory-set threshold voltage (V_TH), the reset output remains asserted for the reset timeout period and then de-asserts, allowing the target microcontroller or microprocessor to leave the reset state and begin operating. The MAX16161 reset output is guaranteed to remain asserted until after a valid V_CC is achieved. This feature is important to avoid low-voltage cores leaving the reset state during power-up or power-down. This design also improves performance when using the MAX16161 as a simple power supply sequencer.
