TI DRV8802－Q1汽车直流马达驱动参考设计TIDA－01357
TI公司的DRV8802-Q1是汽车电子1.6A双路无刷DC马达驱动器,具有两个H桥驱动器.输出驱动器包括可配置成H桥的N沟功率MOSFET,每和H桥提供1.1A RMS或峰值电流1.6A,满足AEC-Q100规范,工作温度–40℃到125℃,主要用在汽车HVAC,汽车阀门和汽车娱乐系统.本文介绍了DRV8802-Q1主要特性,功能框图和应用电路,以及参考设计TIDA-01357主要特性,框图,电路图,材料清单和PCB设计图和合成图.
The DRV8802-Q1 device provides an integrated motor driver solution for automotive applications. The device has two H-bridge drivers, and is intended to drive DC motors. The output driver block for each consists of N-channel power MOSFET’s configured as H-bridges to drive the motor windings. The DRV8802-Q1 device can supply up to 1.6-A peak or 1.1-A RMS output current (with proper heatsinking at 24 V and 25℃) per H-bridge.
A simple parallel digital control interface is compatible with industry-standard devices. Decay mode is programmable to allow braking or coasting of the motor when disabled.Internal shutdown functions are provided for over current protection, short circuit protection, under voltage lockout and overtemperature. The DRV8802-Q1 device is available in a 28-pin HTSSOP package with PowerPAD (Eco-friendly: RoHS & no Sb/Br).
