Maxim Integrated MAX16161 nanoPower Supply Supervisor is an ultra-low current, single-channel supervisory IC with 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 (VTH), the reset output remains asserted for the reset timeout […]
