The DRV8402 can operate at up to 500 kHz switching frequency while still maintains precise control and high efficiency. It also has an innovative protection system integrated on-chip, safeguarding the device against a wide range of fault conditions that could damage the system. These safeguards are short-circuit protection, overcurrent protection, undervoltage protection, and two-stage thermal protection. The DRV8402 has a current-limiting circuit that prevents device shutdown during load transients such as motor start-up. A programmable overcurrent detector allows adjustable current limit and protection level to meet different motor requirements. The DRV8402 has unique independent supply and ground pins for each half bridge, which makes it possible to provide current measurement through external shunt resistor and support multiple motors with different power supply voltage requirements.
