MOSFET Driver
The NCP81155 is a high−performance dual MOSFET gate driver
in a small 3 mm x 3 mm package, optimized to drive the gates of both
high−side and low−side power MOSFETs in a buck or buck−boost
application. 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 3 mm x 3 mm DFN8 Thermally−Enhanced
Package
• VCC Range of 4.5 V to 13.2 V
• Integrated Bootstrap Diode
• Compatible with 3.3 V and 5 V PWM Inputs
• Bi−Directional Enable Feature Pulls Enable Pin low during a
UVLO Fault.
• Adaptive Anti−Cross Conduction Circuit Protects against
Cross−Conduction during FET Turn−on and Turn−off
• Output Disable Control Turns Off Both MOSFETs
• VCC Undervoltage Lockout
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
Typical Applications
• E−Cigarettes
• Unmanned Aerial Vehicles (UAV)
