DRV8802-Q1主要特性 功能框图和应用电路
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).

the tida-01357 ti design offers a solution for dcmotors by using the drv8802-q1 device to controlautomotive hvac flap actuators or dampers. thisdesign demonstrates a cost-effective motor driversolution for six flap actuator where all six motors canbe driven simultaneously with an output current up to0.4 a per motor. this reference design maintains asmall solution size and low quiescent current inaddition to offering reverse battery and load dumpprotection, all of which are highlighted in this guide.brushed-dc motors or stepper motors. this ti design offers a solution for dc-motor-based flap actuators.
the end goal is to develop a cost-effective motor driver solution for six-flap actuators that can be drivensimultaneously. this design includes protection features against load dump conditions and reverse batteryconditions and maintains a small solution size and low quiescent current at the same time.
the tida-01357 has been designed with a focus on the following points:
• simultaneously driving six brushed-dc motors for a flap actuator
• capability to survive reverse battery and load dump conditions (12-v system)
• low quiescent current
• compact design and high performance
• use of a diagnostics feature (output short detect)
