DESCRIPTION

· The TF23892M is a three-phase gate driver IC for high voltage, high-speed applications, driving N-channel MOSFETs and IGBTs in a half-bridge configuration.

· It features a high voltage process enabling high sides to switch up to 600V in bootstrap operation.

· Logic inputs are compatible with TTL and CMOS levels (down to 3.3V), enabled low for high noise environments.

· Includes shoot-through protection, undervoltage lockout (UVLO) for VCC and VBS, and overcurrent protection.

· Available in SOIC-28 package, operating from -40°C to +125°C.

FEATURES

· Three floating high-side drivers in bootstrap operation up to 600V.

· Output current capability: 350mA source / 650mA sink.

· Outputs tolerant to negative transients, dV/dt immune.

· Logic input 3.3V capability.

· Internal deadtime of 290ns for MOSFET protection.

· Wide gate driver supply voltage range: 10V to 20V.

· Matched propagation delay for all channels.

· Outputs out of phase with inputs.

· Schmitt triggered logic inputs.

· Cross conduction prevention logic.

· Undervoltage lockout for all channels.

· Overcurrent protection shuts down drivers.

· Extended temperature range: -40°C to +125°C.
