BTS7960 Motor driver module 43A

Descriere

The BTS 7960 is a fully integrated high current half bridge for motor drive applications. It is part of the NovalithICTM 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 overtemperature, overvoltage, undervoltage, overcurrent and short circuit

The module has the following functions:

1.Overvoltage lock up;

2.Undervoltage shut-down;

3.Overtemperature protection;

4.Current limitation;

5.Short-circuit protection;
