MX512H

- H-bridge circuit topology with integrated N-channel and P-channel power MOSFETs, optimized for driving inductive loads such as coils and motors. - Integrated over-temperature protection: shuts off load current when internal temperature exceeds the set threshold (typical 150°C); resumes normal operation when junction temperature drops back to the preset level (typical 130°C). Note: no short-circuit protection is provided — output-to-GND, output-to-supply, or output-to-output shorts may cause device damage. Avoid short-circuit conditions during use, or implement current-limiting measures to prevent such damage. - Logic supply VCC and power supply VDD are fully independent internally. Route them separately in layout; do NOT connect VCC and VDD directly together, as the high voltage on VDD may damage the VCC rail.
