Texas Instruments TPS79801-Q1 | Demoboard TIDA-00357

Description

This automotive wireless external mirror control reference design showcases a proof-of-concept solution for an automotive power side view mirror that communicates wirelessly with a control switch. Using TI's automotive-qualified BLE + MCU CC2541-Q1 system-on-chip solution, this reference design enables cost, weight, and fuel savings by replacing expensive and heavy cable harnesses. This SoC also pairs seamlessly with TI's integrated H-bridge motor driver solutions, DRV8801-Q1 and DRV8802-Q1, for fold and mirror position adjustment features. Also, to drive the mirror's heating element, TI's single channel integrated smart FET TPS1H100B-Q1 is used.

Features

• AEC-Q100 qualified devices
• Automotive-qualified CC2541-Q1 available (Note: There is a slight pinout change from CC2541)
• Allows the replacement of wires through a robust and mature Bluetooth ultra-low power SoC solution with full Bluetooth low energy certification
• Single H-bridge motor driver and dual H-bridge motor driver solutions with integrated protection features of overcurrent, thermal, and under voltage lockout for higher system reliability
• Wide input voltage range 3V to 50V LDO for direct battery connection with integrated reverse battery protection
• Functionality in start-stop environments
