Reference Designs
12-V: 15-W Power limit: single driver-based stepper: brushed DC and actuator drive reference design
Texas Instruments
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 MCUMotor or load control through I2C line reduces the number of MCU pins requiredIncreased safety and reliability with precise power limit (Open load detect: over current: short circuit: over temperature: surge and ESD protection
