Description
The BTN7970 is a integrated high current half bridge for motor
drive applications. It is part of the NovalithIC™ family containing one
p-channel highside MOSFET and one n-channel lowside MOSFET with
an integrated driver IC in one package. Due to the p-channel highside
switch the need for a charge pump is eliminated thus minimizing EMI.
Interfacing to a microcontroller is made easy by the integrated driver IC
which features logic level inputs, diagnosis with current sense, slew rate
adjustment, dead time generation and protection against over-
temperature, overvoltage, undervoltage, overcurrent and short circuit.
The BTN7970 provides a cost optimized solution for protected high
current PWM motor drives with very low board space consumption.
