Product details

6-TDFN package and thermal integration

The MAX16839ATT+T comes in a 6-WDFN exposed pad package (3x3 mm footprint, 6-TDFN supplier device code).

100 mA linear regulation with PWM dimming

This is a linear (constant-current) LED driver with an integrated switch — no external inductor or diode needed. The single output delivers up to 100 mA per channel, regulated by an external resistor. Dimming is controlled by a PWM signal on the dedicated pin, which toggles the output on and off at the PWM frequency while maintaining the set current amplitude.

Supply voltage spans 5 V to 40 V, covering automotive battery rails (12 V nominal, 24 V truck, 36 V truck transient) and industrial 24 V supplies. The 40 V maximum supply means the part survives load-dump transients up to that level without external clamping, provided the input rail stays below the abs-max rating.

Frequently asked questions

What is the output current and dimming method for MAX16839ATT+T?

The MAX16839ATT+T delivers 100 mA per channel (single output) using linear constant-current regulation. Dimming is controlled by an external PWM signal applied to the dedicated dimming pin — the output toggles on/off at the PWM frequency while the current amplitude stays fixed.

What supply voltage range and temperature grade does MAX16839ATT+T support?

Supply voltage range is 5 V to 40 V, covering automotive 12 V and 24 V systems. Operating temperature is -40°C to +125°C, consistent with AEC-Q100 Grade 1 — suitable for under-hood and exterior automotive LED modules.
