The IC integrates a singular safety attribute

已有 172 次閱讀 2020-5-14 17:11

IC integrates 6 MOSFET half-bridge outputs and two half-bridge gate drivers with protection and diagnostic functions that enrich security, simplify style, and preserve area.Like a total centralized answer for electronically driving motor vehicle locks from the body-control module (BCM), the L99UDL01 replaces many individual motor motorists and associated analog and passive elements though providing a lot more sophisticated features.

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 safety attribute that overrides standard procedure inside the celebration of an accident to help make sure 1st responders could have accessibility to your car. Incorporating more price are pWM output-current regulation and high-level diagnostics able of detecting about present, open up load, short to battery, and short to floor. The load-integrity checks is usually finished with out actuating the load.

The 6 built-in MOSFET fifty percent bridges may be related independently or as two channels made up of approximately a few 50 % bridges in parallel to share higher-current masses. The output MOSFETs are absolutely secured and have low RDS(ON) to spice up electrical power efficiency and simplicity thermal management. Crucial parameters are adjustable to ensure optimum functionality, such as the on-time length, off-state fault detection, and output-current magnitude and course. The programmable present limit allows designers reduced anxiety on door-lock motors to reinforce dependability.

The 2 half-bridge gate drivers improve overall flexibility by permitting designers to attach their decision of N-channel MOSFETs or Intelligent Electrical power equipment to control added high-powered hundreds. The motorists incorporate active recirculation that minimizes power dissipation. Security for the exterior ability gadgets can be built-in, such as drain-source recent checking and off-state fault detection.
