High Frequency Half-Bridge Gate Driver
Features
Description
 D
rives two N-channel MOSFETs in a half bridge
configuration
 Floating high-side driver in bootstrap operation to 50V
 1.5A source / 2.5A sink output current capability
 Internal boostrap diode included
 Undervoltage lockout for high and low side drivers
 Delay matching a typical of 5ns
 Propagation delay a typical of 35ns
 Ultra low standby current (<1mA)
 Logic input (HIN, LIN, and EN) 3.3V capability
 Extended temperature range: -40°C to +125°C
 Space saving TDFN-10 3x3mm package
The TF0507 is a high frequency gate driver capable of
driving N-channel MOSFETs in a half bridge configuration.
The floating high-side driver can switch to 50V in a
bootstrap configuration.
The TF0507 logic inputs are compatible with standard
TTL and CMOS levels (down to 3.3V) to interface easily
with MCUs. UVLO for high side and low side will protect
MOSFET with loss of supply. Also to protect MOSFETs, cross
conduction prevention logic prevents the HO and LO to be
on at the same time.
Fast and well matched propagation delays allow a
higher switching frequency, enabling a smaller, more
compact power switching design using smaller associated
components. Also to minimize space an internal boostrap
diode is included and the TF0507 comes in a space-saving
TDFN-10 package. It operates over an extended -40 °C to
+125 °C temperature range.
Applications
 BLDC Motor Drivers
 Battery Powered Hand Tools
 DC/DC converters
 eCig devices
