# 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 Semicon-
ductor and indicates an 8-lead surface mount package,
SO-8.
Pin Description (High-Side, LM3812)
Pin
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 A).
6
PWM
PWM output indicates the current magnitude and direction.
7
GND
Ground
8
GND
Ground
