TF1503U
Half-Bridge Gate Driver
Features
Description
Floating
high-side driver in bootstrap operation to 600V
Drives
two N-channel MOSFETs or IGBTs in a half bridge
configuration
Designed for enhanced performance in noisy motor
applications
300mA source/550mA sink output current capability
Outputs tolerant to negative transients
Internal dead time of 420ns to protect MOSFETs
Wide low side gate driver supply voltage: 10V to 20V
Logic input (HIN and LIN*) 3.3V capability
Schmitt triggered logic inputs
Undervoltage lockout for VCC (logic and low side supply)
Extended temperature range: -40°C to +125°C
The TF1503U is a high voltage, high speed gate
driver capable of driving N-channel MOSFETs and IGBTs
in a half bridge configuration. TF Semiconductors’s
high voltage process enables the TF2103U high side to
switch to 250V in a bootstrap operation.
The TF1503U 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. TF1503U has a
fixed internal deadtime of 420ns (typical).
The TF1503U is offered in a SOIC-8(N) package and
operates over an extended -40 °C to +125 °C temperature
range.
