CSR produt introduction


Lots of names to call CSR : Milli-Ohm, Current Sensing Resistor, Shunt Resistor.

Function:
Current Sensing Resistor (CSR) is placed on a current circuit and it is used for monitor the current flow by measuring the voltage drop across the path. The current sensor outputs a voltage drop signal to control IC and this functional IC will release the signal to MOS for on/off operation.
In response to suffer bigger current requirement, it is a trend to choose more lower resistance, but low resistance bring a very small signal, and it is a must to use OCP , VR or MCU to modify the function after signal amplification. The typical application like PFC (Power Factor Correction) on PCM or BMS battery module.

Product:
Our CSR (Shunt Resistor) products are more focus on more higher power application and chip size from 2512(3W), 3920(5W), 5930(7~10W), 8420(15W) …to customized shape. The main resistance values from 0.1mΩto 1.0mΩ are used for industrial field, battery protection, electronic components, military and aerospace.
