TIDA-010004
12-V, 15-W Power limit, single driver-based stepper, brushed DC and actuator drive reference design
TIDA-010004
Overview
This reference design demonstrates a multi-load drive using one driver chip in multiple configurations enabling reduced inventory. The multiple loads include one bipolar stepper motor, one brushed DC motor, and three actuator or solenoid loads driven from a 12-V DC supply. The design shows less than two percent accuracy error in input current limit, that helps to achieve a precise power limit for helping easy qualification as a low-power circuit, defined by IEC 60335-1. This reference design incorporates enhanced protections like open load detect, noise tolerant short circuit, overcurrent, overvoltage, undervoltage, overtemperature, surge and ESD protection all which helps to achieve a reliable and robust system design.
Features
- Operates from 4.5V to 16V, supporting multiple loads including bi-polar stepper motor (0.5-ARMS), brushed DC motor (1.2-ARMS), solenoids and actuators (0.2-ARMS)
- Detailed fault diagnosis and multi-slave operation through I2C using a single MCU
- Motor or load control through I2C line reduces the number of MCU pins required
- Increased safety and reliability with precise power limit (<15 W) using eFuse
- Open load detect, over current, short circuit, over temperature, surge and ESD protection
