BTN9970LV
The MOTIX™ BTN9970LV is an integrated high current half bridge with low path resistance for motor drive applications.
The MOTIX™ BTN9970LV is part of the MOTIX™ (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, undervoltage, overcurrent and short circuit. The MOTIX™ BTN9970LV provides a cost optimized solution for protected high current PWM motor drives with very low board space consumption. This device comes in a small HSOF-7-1 package.
Key difference to BTN9990LV:
- Path resistance
