LMP8645/LMP8645HV  
Precision High Voltage Current Sense Amplifier  
General Description  
Features  
The LMP8645 and the LMP8645HV are precision current  
sense amplifiers that detect small differential voltages across  
a sense resistor in the presence of high input common mode  
voltages with a supply voltage range from 2.7V to 12V.  
Typical values, TA = 25°C  
High common-mode voltage range  
LMP8645  
LMP8645HV  
Supply voltage range  
-2V to 42V  
-2V to 76V  
2.7V to 12V  
The LMP8645 accepts input signals with common mode volt-  
age range from -2V to 42V, while the LMP8645HV accepts  
input signal with common mode voltage range from -2V to  
76V. The LMP8645 and LMP8645HV have adjustable gain  
for applications where supply current and high common mode  
voltage are the determining factors. The gain is configured  
with a single resistor, providing a high level of flexibility, the  
accuracy could be as low as 2% (max) including the gain set-  
ting resistor. The output is buffered in order to provide low  
output impedance. This high side current sense amplifier is  
ideal for sensing and monitoring currents in DC or battery  
powered systems, excellent AC and DC specifications over  
temperature, and keeps errors in the current sense loop to a  
minimum. The LMP8645 is an ideal choice for industrial, au-  
tomotive and consumer applications, and it is available in  
TSOT-6 package.  
Gain configurable with a single resistor
