DESCRIPTION

SENSES BUS VOLTAGES FROM 0V TO +26V  
The INA209 is a high-side current shunt and power  
monitor with an I2C interface. The INA209 monitors  
•
•
REPORTS CURRENT, VOLTAGE, AND  
POWER; STORES PEAKS  
both shunt drop and shunt bus voltage.  
A
programmable calibration value, combined with an  
internal multiplier, enables direct readouts in  
amperes. An additional multiplying register calculates  
power in watts. The INA209 features two separate,  
onboard watchdog capabilities: a warning comparator  
and an over-limit comparator. The warning  
comparator is useful for monitoring lower warning  
limits and incorporates a user-defined delay. The  
over-limit comparator assists with monitoring upper  
limits that could require immediate system shutdown.

VS  
The INA209 also includes an analog comparator and  
a programmable digital-to-analog converter (DAC)  
that combine to provide the fastest possible  
responses to current overload conditions.  
The INA209 can be used together with hot swap  
controllers that already use a current sense resistor.  
The INA209 full-scale range can be selected to be  
either within the hot-swap controller sense limits, or  
wide enough to include them.  
VIN+ VIN-  
(Supply Voltage)  
The INA209 senses across shunts on buses that can  
vary from 0V to 26V. The device uses a single +3V to  
+5.5V supply, drawing a maximum of 1.5mA of  
supply current. It is specified for operation from  
–25°C to +85°C.
