NCP81253 Datasheet 5V MOSFET Driver Compatible

Manufacturer: onsemi

Overview: NCP81253 5 V 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 external components. A VCC UVLO function guarantees the outputs are low when the supply voltage is low.
