BTN7971B half bridge motor driver

The BTN7971B 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 overtemperature, overvoltage, undervoltage, overcurrent and short circuit. The BTN7971B provides a cost optimized solution for protected high current PWM motor drives with very low board space consumption.

Summary of Features:

  • Path resistance of max. 30.5 mΩ @ 150 °C (typ. 16 mΩ @ 25 °C) High Side: max. 12.8 mΩ @ 150 °C (typ. 7 mΩ @ 25 °C) Low Side: max. 17.7 mΩ @ 150 °C (typ. 9 mΩ @ 25 °C)
  • Low quiescent current of typ. 7 μA @ 25 °C
  • PWM capability of up to 25 kHz combined with active freewheeling
  • Enhanced switching speed for reduced switching losses
  • Switched mode current limitation for reduced power dissipation in overcurrent
  • Current limitation level of 50 A min. / 70 A typ. (low side)
  • Status flag diagnosis with current sense capability
  • Overtemperature shut down with latch behavior
  • Overvoltage lock out
  • Undervoltage shut down
  • Driver circuit with logic level inputs
