Key Features
- Advanced Diagnostic Capabilities: Includes reporting via SPI for conditions such as charge pump undervoltage, overvoltage, short to ground, short to VPWR, open load, temperature warning, and overtemperature shutdown.
- Overvoltage Protection: Places the load in high-side recirculation (braking) mode with notification in H-bridge mode.
- Internal Protection: For overtemperature, undervoltage, and short-circuit by signaling the error condition and disabling the outputs.
- Current Sensing and Limiting: Provides an analog feedback signal proportional to the load current and implements current limiting PWM to reduce overload conditions.
- Integrated Voltage Regulators: Supplies the logic and protection functions internally, reducing the need for external supplies.
Applications
