The United States listed in the letter EEPROM programmable LED driver IC

[BP] reported that the United States and the United States and the United States Products (Maxim Integrated) introduced a built-in non-volatile register, programmable adjustment of LED current drive IC LED (MAX16816). The working temperature range of 40 ~ 125 C. Automotive and general purpose lighting equipment.

The EEPROM registers can be accessed through the 1-wire interface, uses an external microcontroller to write on. Circuit designers and other programs can be written to adjust the output rise time of the soft start function of the time, LED current adjustment, slope compensation, blanking time, built-in PWM oscillator on / off, etc..

Dimming using external input analog signal or PWM signal. The dimming ratio is 1000:1. The input voltage range is from 5.9 to 76V. Built in switch regulator circuit can be set to reduce pressure, boost and lift pressure. Switching frequency can be set between 125k ~ 500kHz. Built in differential current sense amplifier and driver for external MOSFET. It also has the functions of short circuit protection and overheat protection.

Package using 32 terminal TQFN. 1000 more than the bulk of the reference price of $2.33 purchase.
