The MAX42500 is a system-on-a-chip (SoC) power system monitor with up to seven voltage monitor inputs. Each input has programmable overvoltage (OV)/undervoltage (UV) thresholds of between 2.5% and 10% with ±1.3% accuracy over the full temperature range. Two of the inputs have a separate remote ground-sense input and support dynamic voltage scaling (DVS) through the integrated I2C interface.
The MAX42500 features a programmable flexible power sequence recorder (FPSR) that stores power-up and power-down timestamps separately and supports on/off and sleep/standby power sequences. The MAX42500 also contains a programmable challenge/response watchdog, which is accessible through the I2C interface along with a configurable RESET output.
The MAX42500 enhances reliability while significantly reducing system size and component count as compared to using separate ICs or discrete components. The MAX42500 is suitable for use in safety functions up to SIL 3 and designed to operate over the full temperature range of −40°C to +125°C.
