General Description
The A4900 is a high-voltage, high-speed, power IGBT or MOSFET driver providing three independent half-bridge channels for three-phase applications.
A bootstrap capacitor is used to provide the above battery supply voltage required for N-channel MOSFETs or IGBTs used as high current switches.
