IC integrates six MOSFET half-bridge outputs and two half-bridge gate drivers with security and diagnostic capabilities that improve protection, simplify layout, and help save place.As a complete centralized resolution for electronically driving automobile locks from a body-control module (BCM), the L99UDL01 replaces numerous specific motor drivers and affiliated analog and passive components though offering additional advanced functionality.
Discover our half bridge driver, with excellent ruggedness and noise immunity, they are perfect for motor drives, home appliance and battery powered applications.The IC integrates a singular protection function that overrides typical operation during the event of an accident that can help make sure very first responders could have entry on the car. Including more benefit are pWM output-current regulation and high-level diagnostics capable of detecting around present-day, open up load, brief to battery, and small to floor. The load-integrity checks is usually completed without having actuating the load.
The six integrated MOSFET 50 percent bridges can be related independently or as two channels that contains as much as 3 half bridges in parallel to share higher-current masses. The output MOSFETs are absolutely shielded and possess minimal RDS(ON) to spice up vitality performance and ease thermal administration. Important parameters are adjustable to guarantee best general performance, such as the on-time duration, off-state fault detection, and output-current magnitude and direction. The programmable existing limit lets designers decreased pressure on door-lock motors to enhance reliability.
The two half-bridge gate drivers boost versatility by permitting designers to attach their choice of N-channel MOSFETs or Intelligent Electric power devices to manage additional high-powered loads. The drivers integrate active recirculation that minimizes electric power dissipation. Security to the external electric power units can be built-in, such as drain-source latest checking and off-state fault detection.
