Full Bridge Mosfet Driver

DRV8701 Brushed DC Motor Full-Bridge Gate Driver 1 Features 2 Applications 1• Single H-Bridge Gate Driver • Industrial Brushed-DC Motors. The DRV8701 is a single H-bridge gate driver that – 6-mA to 150-mA Source Current uses four external N-channel MOSFETs targeted to. The L6205, L6206, L6207 are dual full bridge drivers ICs specifically developed. With MOSFET (DMOS) devices, unlike bipolar transistors, current under short.

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).

Product Details 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. Its unique adaptive protection against shoot-through currents eliminates all matching requirements for the two MOSFETs. This greatly eases the design of high efficiency motor control and switching regulator systems. During low supply or start-up conditions, the undervoltage lockout actively pulls the driver outputs low to prevent the power MOSFETs from being partially turned on. Programma generator golosa en.

The 0.5V hysteresis allows reliable operation even with slowly varying supplies. The LT1162 is a dual version of the LT1160 and is available in a 24-pin PDIP or in a 24-pin SO Wide package. Applications • PWM of High Current Inductive Loads • Half-Bridge and Full-Bridge Motor Control • Synchronous Step-Down Switching Regulators • 3-Phase Brushless Motor Drive • High Current Transducer Drivers • Class D Power Amplifiers.
