Each input has programmable OV/UV thresholds of between 2.5% and 10% with ±1% accuracy. Two of the inputs have a separate remote ground-sense input and support DVS through the integrated I2C interface. ● Small Solution
• 2.35V to 5.50V Operating Supply Voltage
• Only One External Component Required
• 150μA Operating Current
• 8μA Power-Down Mode The MAX20480 contains a programmable flexible power
sequence recorder (FPSR). This recorder stores power-up
and power-down timestamps separately, and supports on/
off and sleep/standby power sequences. The MAX20480
also contains a programmable challenge/response watchdog, which is accessible through the I2C interface, along
with a configurable RESET output.
The MAX20480 improves reliability while significantly reducing system size and component count, compared to
separate ICs or discrete components. The MAX20480
meets ASIL-D reliability when used with a supervisory
controller. The device is designed to operate over the ambient temperature range of -40°C to +125°C. Applications
