Full Bridge Gate Driver
Easy tv usb 20 analog tv receiver driver. The FL73282, a monolithic half bridge gate-drive IC, can drive MOSFETs and IGBTs that operate up to +900 V. Fairchild’s high-voltage process and common mode noise canceling technique provides stable operation of the high-side driver under high-dVS/dt noise circumstances. An advanced level-shift circuit allows high-side gate driver operation up to V S=-9.8 V (typical) for V BS=15 V. The UVLO circuits for both channels prevent malfunction when V CC or V BS is lower than the specified threshold voltage. Output drivers typically source/sink 350 mA / 650 mA, respectively, which is suitable for all kinds of half- and full-bridge inverters.
Motor driver for home appliances Factory automation Industrial drives and fans HID ballasts Power supply units Description The L6393 is a high voltage device manufactured with the BCD™ “offline” technology. It is a single chip half bridge gate driver for the N-channel power MOSFET or IGBT. The LT1160/LT1162 are cost effective half-/full-bridge N-channel power MOSFET drivers. The floating driver can drive the topside N-channel power MOSFETs operating off a high voltage (HV) rail of up to 60V. The internal logic prevents the inputs from turning on the power MOSFETs in a half-bridge at the same time.

The A4957 is a full-bridge controller for use with external N-channel power MOSFETs and is specifically designed for applications with high-power inductive loads such as brush DC motors. A unique charge pump regulator provides full ( >10 V ) gate drive for battery voltages down to 7 V and allows the A4957 to operate with a reduced gate drive, down to 4.5 V. A bootstrap capacitor is used to provide the above battery supply voltage required for N-channel MOSFETs. A unique bootstrap charge management system ensures that the bootstrap capacitor is always sufficiently charged to supply the high-side gate drive circuit. Each of the power MOSFETs is controlled independently but all are protected from shoot-through by dead time that is userconfigured by an external resistor.
Integrated diagnostics provide indication of undervoltage and overtemperature faults. The A4957 is supplied in a 24-contact 4 mm × 4 mm × 0.75 mm QFN with an exposed pad for enhanced thermal dissipation. It is lead (Pb) free, with 100% matte tin leadframe plating (suffix –T).
