TF21814-TUH

Advance Info TF21814 High-Side and Low-Side Gate Driver Features Description  F  loating high-side driver in bootstrap operation to 600V  Drives two N-channel MOSFETs or IGBTs in a half bridge configuration  1.9A source / 2.3A sink output current capability  Outputs tolerant to negative transients  Wide low side gate driver supply voltage: 10V to 20V  Logic input (HIN and LIN) 3.3V capability  Schmitt triggered logic inputs with internal pull down  Undervoltage lockout for high and low side drivers  Extended temperature range: -40°C to +125°C The TF21814 is a high voltage, high speed gate driver capable of driving N-channel MOSFETs and IGBTs in a half bridge configuration. TF Semiconductor’s high voltage process enables the TF21814’s high side to switch to 600V in a bootstrap operation. The TF21814 logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with controlling devices. The driver outputs feature high pulse current buffers designed for minimum driver cross conduction. The TF21814 is offered in PDIP-14 and SOIC-14(N) packages and operate over an extended -40 °C to +125 °C temperature range.
