VNH7070BASTR, STMicroelectronics, Automotive‑Grade H‑Bridge Brushed DC Motor Driver IC

STMicroelectronics, Automotive‑Grade H‑Bridge Brushed DC Motor Driver IC, VIPower series, AEC‑Q100 automotive qualified, SO‑16N (SOIC‑16) surface‑mount package, tape‑and‑reel TR packaging.

Key Parameters

Drive Architecture: Integrated H‑bridge full‑bridge driver for brushed DC motors

Supply Voltage VCC: 4V‑28V, maximum withstand voltage 38V

Continuous Output Current: 15A with higher peak current; single device drives one DC motor

Package: SOIC‑16 (SO‑16N), 16‑pin surface‑mount. Suffix R in TR denotes tape‑and‑reel delivery

Input Logic Level: 3V CMOS‑compatible, directly interfacing with MCU I/O ports such as STM32

PWM Speed Control: Up to 20 kHz PWM frequency

Temperature: ‑40℃ ~ +150℃ (junction temperature), AEC‑Q100 automotive qualified

On‑state Resistance: Typical 70 mΩ per bridge arm

Protection Features: Under‑voltage shutdown, over‑voltage clamping, thermal shutdown, cross‑conduction prevention, current‑limit power protection, short‑to‑ground / short‑to‑supply protection, ground‑loss protection. The CS pin provides motor‑current sense feedback and fault diagnostic output.

MSL Rating: MSL3, Moisture Sensitivity Level 3

Main Functions

H‑Bridge Driving: Controls brushed DC motor forward, reverse, brake and stop. INA and INB pins set rotation direction; PWM pin implements speed regulation.

Current Sensing: The CS pin outputs an analog signal proportional to motor current. The MCU can sample this signal for over‑current detection and stall diagnosis.

Comprehensive built‑in protections reduce external power components and simplify peripheral circuits.

Supports low‑power standby mode; configurable as two independent half‑bridges.
