FUNCTION
Current-Regulated Output. Connect pin 1 to pin 16.
Positive Input Supply. Bypass IN with a 0.1μF (min) capacitor to GND. Connect pin 2 to pin 3.
Not Internally Connected
Positive Input of the Internal Differential Amplifier. Connect the current-sense resistor between CS+
and CS- to program the output current level.
Negative Input of the Internal Differential Amplifier. Connect the current-sense resistor between
CS- and CS+ to program the output current level.
+5V Regulated Output. Connect a 0.1μF capacitor from V5 to GND.
Ground
Enable Input. Drive EN high to enable the output.
Exposed Pad. Connect to the ground plane for effective power dissipation. Do not use as the only
ground connection.

Detailed Description
The MAX16800 is a high-current regulator capable of
providing up to a total of 350mA of current to one or
more strings of high-brightness LEDs. A wide operating
input voltage range of +6.5V to +40V makes the
MAX16800 ideal for automotive applications. A +5V
regulated output provides up to 4mA of current to
power external circuitry. In addition, the MAX16800 fea-
tures thermal and output short-circuit protection. The
wide operating voltage range helps protect the
MAX16800 against large transients such as those
found in load-dump situations up to 40V.
The MAX16800 uses a feedback loop to control the out-
put current. The differential voltage across the sense
resistor is compared to a fixed reference voltage, and
the error is amplified to serve as the drive to the internal
