AT8870

The AT8870 is a H-bridge motor driver IC designed to control DC motors or stepper motors in low-voltage applications. It supports a voltage range of 2.7V to 5.5V and delivers a continuous output current of up to 1.5A, making it suitable for small robotics, toys, and portable devices.
Key features include:
- PWM control for speed regulation.
- Built-in protection against overcurrent, overtemperature, and undervoltage.
- Low standby current for power efficiency.
- Compact package (e.g., SOP-8) for space-constrained designs.
The AT8870 is controlled via IN1/IN2 logic inputs, allowing simple forward/reverse and brake functions. It’s commonly used in battery-powered systems due to its low-voltage operation.
