NCP81258
feature allows for a high- efficiency solution even at light load conditions. VCC UVLO ensures the MOSFETs are off when supply voltages are low. A bi- directional Enable pin provides a fault signal to the controller when a UVLO fault is detected.
Features
- Space- efficient 2 mm x 2 mm DFN8 Thermally- enhanced Package
- VCC Range of 4.5 V to 13.2 V
- Internal Bootstrap Diode
- 5 V 3- stage PWM Input
- Zero Current Detect Function Provides Power Saving Operation during Light Load Conditions
- Bi- directional Enable Feature pulls Enable Pin Low during a UVLO
Fault
- Pre- OVP Function Protects Load during HS FET Short
- Adaptive Anti- cross Conduction Circuit Protects against
Cross- conduction during FET Turn- on and Turn- off
- Output Disable Control Turns Off Both MOSFETs via Enable Pin
