NCP81155

NCP81155 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) www.onsemi.com 1 DFN8 MN SUFFIX CASE 506BJ MARKING DIAGRAM 1 81155 ALYWG G 81155 A L Y W G = Specific Device Code = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package (Note: Microdot may be in either location) PIN CONNECTIONS BST 1 8 DRVH PWM 2 EN 3 FLAG 9 7 SW 6 GND VCC 4 (Top View) 5 DRVL ORDERING INFORMATION Device Package Shipping† NCP81155MNTXG DFN8 3000 / Tape & Reel (Pb−Free) †For information on tape and reel specifications, including part orientation and tape sizes, please refer to ou...
