The STMicroelectronics L99LDLH32TR is a 32-channel LED driver designed for automotive and lighting applications. This linear driver utilizes PWM dimming for precise control of LED intensity.
Key electrical specifications include an operating voltage range starting at 5.5V and a current output of 24mA per channel. The device features a constant current topology and does not have internal switches, requiring external components for power stages.
Operating within a wide temperature range of -40°C to 150°C (TJ), the L99LDLH32TR is suitable for demanding environments. It is packaged in a 48-VFQFPN (7x7mm) with a surface mount type, designed for efficient heat dissipation and reliable soldering.
Compliance includes RoHS3, REACH unaffected, and MSL 1. The part is intended for applications in automotive lighting systems and general industrial LED lighting where robust control is necessary.
