NCP81253 Datasheet, PDF (1/10 Pages) ON Semiconductor – 5 V MOSFET Driver Compatible

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.
Features
• Space−efficient 2 mm x 2 mm DFN8 Thermally−enhanced Package
• VCC Range of 4.5 V to 5.5 V
• Internal Bootstrap Diode
• 5 V 3−stage PWM Input
• Diode Braking Capability via EN Mid−state
• 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
• VCC Undervoltage Lockout
• These devices are Pb−free, Halogen−free/BFR−free and are RoHS
compliant
Typical Applications
• Power Solutions for Notebook and Desktop Systems
