Pin Description
PIN
NAME
FUNCTION
1
RSB
Current-Sense Amplifier Input Stage Supply. Connect to either RS+ or RS-.
2
RS+
Current-Sense Amplifier Positive Input
3
RS-
Current-Sense Amplifier Negative Input
4
N.C.
No Connection. Not internally connected.
5
GND
Ground
6
SHDN
Shutdown Logic Input. Connect to GND to reduce quiescent current to 1A. Connect to VDD for normal operation.
7
REF
Reference Voltage Input. Connect to an external voltage to provide a bidirectional current-sense output. Connect
to GND for unidirectional operation.
8FB
Gain-Set Feedback Input. Connect an optional noise reduction capacitor between OUT and FB.
MAX9922: Adjustable Gain. Connect a resistive-divider feedback network between OUT, FB, and REF to set the
current-sense amplifier gain. Use an external combination of R1 and R2 resistors for gain = 1 + (R2/R1).
MAX9923T/MAX9923H/MAX9923F: Fixed gain. See the Functional Diagrams.
9
OUT
Voltage Output. VOUT is proportional to VSENSE.
10
VDD
Power-Supply Voltage Input. Bypass to GND with a 0.1F capacitor.
