High Current PN Half Bridge NovalithIC

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.

Features:

• Path resistance of max. 30.5 mΩ @ 150 °C
• Low quiescent current of typ. 7 μA @ 25 °C
• PWM capability of up to 25 kHz combined with active freewheeling
