Part number:

A8522

Manufacturer:

Allegro

File Size:

6.02 MB

Description:

Multi-Channel LED Driver

Features

* AEC-Q100 qualified
* Wide input voltage range of 4.5 to 36 V
* Operates down to 3.9 V (VIN falling) for idle stop, and up to 40 V for load dump
* Integrated boost converter with DMOS switch and OVP protection up to 39 V
* 8 fully integrated LED current sinks

Applications

* The I2C interface allows the user to set the LED currents individually, up to 60 mA per LED channel. Adjacent channels may be combined to drive higher-current LED strings. The PWM dimming duty cycle also is independently controlled for each LED channel. This flexibility makes the A8522 a single sol
