Infineon Technologies MOTIX™ BTN9990LV Motor Control IC


Infineon Technologies MOTIX™ BTN9990LV Motor Control IC contains one p-channel high-side MOSFET and one n-channel low-side MOSFET with an integrated driver IC in one package. The interfacing to a microcontroller is made easy by the integrated driver IC and the EMI is minimized due to the p-channel high-side switch. This integrated driver IC features logic-level inputs, slew-rate adjustments, diagnosis with current sense, dead time generation, protection against overtemperature, undervoltage, overcurrent, and short circuit. The MOTIX™ BTN9990LV IC provides a cost-optimized solution for protected high current PWM motor drives with very low board space consumption. Typical applications include automotive 12V brushed DC motor, seatbelt pre-tensioner, seat control, fuel pumps, power liftgate, sliding door, and HVAC control module.

Features

  • Integration of high power PMOS, NMOS, and driver IC minimizes design and manufacturing effort
