The EHP2604 is a front-end over voltage and over current protection device. It achieves wide input voltage range from 2.5VDC to 40VDC.
The over voltage threshold can be programmed externally or set to internal default setting.
The low resistance of integrated power path nFET switch ensures better performance for battery charging system applications.
It can deliver up to 1A current to satisfy the battery supply system.
It integrates the over-temperature protection shutdown and auto-recovery circuit with hysteresis to protect against over current events.
