DRV8908QPWPRQ1 Automotive H-Bridge Motor Driver
The DRV8908QPWPRQ1 is a highly integrated 48V automotive-qualified H-bridge motor driver from Texas Instruments, designed for precise control of DC motors in automotive body electronics and industrial applications. This advanced driver integrates eight half-bridge outputs capable of delivering continuous currents up to 1.5A per channel (3A peak), supporting a wide range of loads including door modules, seat positioning systems, and HVAC actuators. The device operates from a 4.5V to 48V supply range, making it exceptionally versatile for 12V/24V/48V automotive systems while featuring a 5V/3.3V regulator for microcontroller interfacing.
Engineered for automotive reliability, the DRV8908QPWPRQ1 incorporates comprehensive protection features including overcurrent protection (OCP), overtemperature shutdown (TSD), and undervoltage lockout (UVLO). Its AEC-Q100 Grade 1 qualification ensures operation across the -40°C to +150°C ambient temperature range, critical for under-hood applications. The device utilizes PWM control with 128 microsteps for smooth motor operation and implements current sensing with adjustable gain for precise torque control. Packaged in a 28-pin HTSSOP (PowerPAD™), it offers excellent thermal dissipation while minimizing PCB footprint in space-constrained designs. These features make it ideal for electric power steering pumps, sunroof controls, and advanced driver assistance systems (ADAS) requiring high reliability and diagnostic capabilities.
