# Suffix M indicates that the part is available in Surface Mount package. Suffix X indicates that the part is available in 2.5k units

on Tape and Reel.

* Current is sampled over a fixed interval. The average current during this interval is indicated by the duty cycle of the PWM output

during next interval.

‡ The Package code M08A is internal to National Semiconductor and indicates an 8-lead surface mount package, SO-8.

Pin Description (High-Side, LM3812)

Name

Function

1

SENSE+, V

DD

High side of internal current sense, also supply voltage.

2

SENSE−

Low side of internal current sense.

3

FLTR+

Filter input — provides anti-aliasing for delta sigma modulator.

4

FLTR−

Filter input.

5SD

Shutdown pin. Connected to V

DD through a pull up resistor for normal operation.

When low, the IC goes into a low current mode (typically 3 µA).

6

PWM

PWM output indicates the current magnitude and direction.

7

GND

Ground

8

GND

Ground
