BTF 50060-1TEA Product Brief

Product Brief
Speed PROFET TM – BTF 50060-1TEA
Motor Drive High Side Switch
Key Features
„„
PWM capability of more than 25kHz
„„
6mΩ RON (max. 12mΩ @ 150°C) with
„„
No external bootstrap capacitor
high inrush current
necessary
The BTF 50060-1TEA is a single channel 6mΩ (max. 12mΩ @ 150°C) High
Side Driver, able to be driven by PWM control signals with high frequencies,
such as 25kHz, but also capable of DC operation.
„„ 3.3V and
„„
5V compatible logic inputs
Advanced analog load current sense
signal
„„
The device is housed in PG-TO252-5 (DPAK 5 pin) RoHS compliant package. In
combination with a freewheeling diode, the BTF50060-1TEA can be set up in a
half bridge topology.
Overload and overtemperature
protection, with defined diagnostic
signal
Key Benefits
The device includes protection functions like short circuit and overtemperature
shutdown. Through the IS pin, BTF 50060-1TEA provides an accurate load
current measurement in normal operation and a diagnostic feedback, with
a defined signal, for such events as open load – both in ON and OFF state,
overcurrent and overtemperature.
„„
Reduced power dissipation
„„
Small package for high current motor
drive, less PCB space
„„
Reduced component count and
easier PCB layout
The Speed PROFET TM doesn’t need an external bootstrap capacitor for high
frequency switching.
Applications
„„
Most suitable for driving motors, valves, and coils, e.g. fuel pump
„„
Capable of PWM switching frequency of 25kHz and above
