NCP81253: MOSFET Driver Compatible with Single-Phase IMVP8 Controllers
The NCP81253 is a high-performance dual MOSFET gate driver in a small 2 mm x 2 mm package, optimized to drive the gates of both high-side and low-side power MOSFETs in a synchronous buck converter. The driver outputs can be placed into a high-impedance state via the tri-state PWM and EN inputs. The NCP81253 comes packaged with an integrated boost diode to minimize the number of external components. A VCC UVLO function guarantees the outputs are low when the supply voltage is low.
Features- Internal bootstrap diode
- 5 V 3-stage PWM input
- Adaptive anti-cross-conduction circuit
- Diode braking capability
- Output disable control
- VCC undervoltage lockout
| Benefits- Reduces number of external components
- Allows for high-impedance state
- Protects against cross-conduction during FET turn-on and turn-off
- Quickly reduces inductor current
- Ability to turn off both MOSFETs via the Enable pin
- Guarantees outputs are low when supply voltage is low
