2. Wide Operating Voltage: Supports a supply voltage range from 12V to 48V, offering versatility for different applications.
3. Output Current: Capable of delivering up to 1A continuous current per bridge, suitable for low to medium power motors.
4. Protection Features: Includes overcurrent protection and thermal shutdown to prevent damage under fault conditions.
5. High Efficiency: Utilizes DMOS technology for efficient operation and reduced power dissipation.
6. Built-in Flyback Diodes: Protects the device from voltage spikes induced by inductive loads.
7. PWM Control: Supports pulse-width modulation for precise speed and torque control.
8. Compact Package: Available in a multiwatt package, allowing for compact design integration.
9. Cross-conduction Prevention: Ensures safe operation by preventing simultaneous conduction of both high and low-side switches in a bridge.
These features make the L6202 suitable for a variety of motor control applications in automation, robotics, and consumer electronics.
Pinout
1. Out 1A / Out 2A: Outputs for one of the full bridges.
2. Out 1B / Out 2B: Outputs for the other full bridge.
3. Vs: Supply voltage pin.
4. GND: Ground connection.
5. Vref: Reference voltage input used for current control.
6. In 1 / In 2: Logic inputs to control the state of the bridges.
7. Sense A / Sense B: Connections for sensing the current through the load.
8. Bootstrap A / Bootstrap B: Pins for bootstrap capacitors, used to drive the high side of the full bridge.
