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) 参考计划TIDA-01357首要特征: Survives Voltages up to 45 V Withstands Reverse Battery Conditions and LoadDump Conditions (12-V System) Three-Chip Solution to Drive up to Six MotorsSimultaneously (Two DC Motors per IC) Compact Layout; Does Not Require External FETs Low Quiescent Current Components Selected for Automotive Temperatureand Quality 参考计划TIDA-01357应用: Automotive HVAC Flap Actuator and DamperMotor Drive Automotive HVAC Intake Air-Flap Motor Drive 参考计划TIDA-01357电特征: 图3.参考计划TIDA-01357框图 图4.

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,电路图,每和H桥提供1.1A RMS或峰值电流1.6A, 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). DRV8802-Q1首要特征: Qualified for Automotive Applications AEC-Q100 Qualified With the Following Results Device Temperature Grade 1: 40℃ to 125℃ Ambient Operating Temperature Device HBM ESD Classification Level 2 Device CDM ESD Classification Level C4B Dual H-Bridge Current-Control Motor Driver Drives Two DC Motors Brake Mode Two-Bit Winding Current Control Allows Up to 4 Current Levels Low MOSFET On-Resistance 1.6-A Maximum Drive Current at 24 V, short circuit protection,汽车阀门和汽车娱乐体系.本文先容了DRV8802-Q1首要特征,原料清单和PCB计划图和合成图. The DRV8802-Q1 device provides an integrated motor driver solution for automotive applications. The device has two H-bridge drivers,成果框图和应用电路, and is intended to drive DC motors. The output driver block for each consists of N-channel power MOSFETs 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,以嘉拷寮计划TIDA-01357首要特征。
