Extended temperature range: -40°C to +125°C
Description
The TF2104M is a high voltage, high speed gate driver
capable of driving N-channel MOSFETs and IGBTs in a
half bridge configuration. TF Semi’s high voltage process
enables the TF2104M’s high side to switch to 600V in a
bootstrap operation.
The TF2104M 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 TF2104M is offered in PDIP-8 and SOIC-8(N) packages
and operate over an extended -40 °C to +125 °C temperature
range.
