MAX4921B, MAX4919B Datasheet - Maxim Integrated

MAX4921B Battery Power-Up Logic

The MAX4919B/MAX4920B/MAX4921B overvoltage protection controllers protect low-voltage systems against high-voltage faults up to +28V. An internal 1.8A (min) pFET with low RON (100mΩ) switches a battery to the load and also protects the battery against short-circuit faults. When a short circuit occur.

MAX4921B Features

* o Input Overvoltage Protection Up to +28V o Preset Overvoltage Protection Trip Level 6.38V (MAX4919B) 5.80V (MAX4920B) 4.65V (MAX4921B) o Adapter/Car-Kit Auto-Selector o Low-Current Undervoltage Lockout Mode o Internal 1.8A (min) Battery Switchover FET o Integrated Low-Battery Detect o Battery Short
