The Maxim Integrated MAX1800EHJ is a supervisor IC designed specifically for digital camera power-supply sequencing and monitoring. It integrates the supervisory functions needed to manage multiple voltage rails in a compact camera module — power-on reset, voltage monitoring, and sequencing control — in a single Bulk-packaged device. This part is targeted at portable imaging equipment where board space is constrained and reliable power-up sequencing is critical to prevent latch-up or improper sensor initialization.
This IC sequences and monitors the multiple supply rails found in a camera module.
