Diodes' AP9234L incorporates a high accuracy Li+ battery protection chip and a dual N-channel, ultra-low RSS(ON) MOSFET with common drain. It provides rich battery protection features, such as over-charge voltage / current, over-discharge voltage / current, and load short-circuit. The AP9234L has a built-in fixed delay time to minimize external components. Highly accurate detection circuits compensate the internal MOSFET RSS(ON) performance to ensure extremely high over-charge/discharge current limit accuracy at both room- and full-temperature. The AP9234L is available in the U-DFN2535-6 package.
| Features |
|
|
- High voltage CMOS process, up to 24 V (between terminals)
