Full Bridge Gate Driver Ic
The A5929 is a full-bridge controller for use with n-channel external power MOSFETs and is specifically designed for automotive applications. A unique charge pump regulator provides full (10 V) gate drive at battery voltages down to 7 V and allows the A5929 to operate with reduced gate drive at battery voltages down to 5.5 V.
Full Bridge Gate Driver Ic
Analog Devices offers cost-effective, half-/full-bridge MOSFET drivers for motor control, PWM of high current inductive loads, and high current transducer drivers. Unique, adaptive, nonoverlapping gate drives prevent shoot-through currents, which greatly eases the design of high efficiency motor control and switching regulator systems. Gate drivers can be provided either on-chip or as a discrete module. In essence, a gate driver consists of a level shifter in combination with an amplifier. A gate driver IC serves as the interface between control signals (digital or analog controllers) and power switches (IGBTs, MOSFETs, SiC MOSFETs, and GaN HEMTs).
Full Bridge Mosfet Gate Driver Ic
A bootstrap capacitor is used to provide the above battery supply voltage required for n-channel MOSFETs. One logic level input is provided for each of the four power MOSFETs in the full-bridge, allowing motors to be driven with any PWM scheme defined by an external controller.
The power MOSFETs are protected from cross-conduction by integrated crossover control. Motor phase short-to-supply and short-to-ground detection is provided by independent drain-source voltage monitors on each MOSFET.
H-bridge Mosfet Gate Driver Ic
Short faults, supply undervoltage, and chip over-temperature conditions are indicated by a single open drain fault output. The A5929 is supplied in a 24-pin TSSOP power package with an exposed thermal pad (package type LP). This package is available in lead (Pb) free versions, with 100% matte-tin lead frame plating (suffix –T).
