TF2388M-TGH

The TF2388M is a three-phase gate driver IC designed for high voltage three-phase applications, driving N-channel MOSFETs and IGBTs in a half-bridge configuration. High voltage process enables the TF2388M high sides to switch to 600V in a bootstrap operation. The TF2388M logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with controlling devices and are enabled low to better function in high noise environments. The driver outputs feature high pulse current buffers designed for minimum driver cross conduction. The TF2388M offers numerous protection functions. A shoot-through protection logic prevents both outputs being high with both inputs high (fault state), an undervoltage lockout for VCC shuts down all drivers through an internal fault control, and a UVLO for VBS shuts down the respective high side output. The TF2388M is offered in SOIC 20 package and operates over an extended -40 °C to +125 °C temperature range.
