Current-sense amplifier are amplifiers that feature internal precision resistors to create a full differential input. This type of amplifiers are also called as current shunt amplifiers or current shunt monitors. The current-sense amplifiers also feature zero-drift architecture or low offset voltage and low offset drift over temperature. These devices measure small voltage drops across a shunt resistor that is connected to the inputs. The current-sense amplifiers are unidirectional as well as bidirectional, hence it measures current flow in both the direction. Also these amplifiers has two sensing methods such as high-side current sensing and low-side current sensing. The high-side current sensing connects the sensing element between the power supply and load. And the low-side current sensing connects the sensing element between the load and ground. Moreover, the power control and reliability is critical for IoT, automotive, and portable systems and devices where battery powered electronic devices need to control power distribution by monitoring power supply currents. Thus in situations like an overcurrent prevention, extending battery life, monitoring ground faults, current sensing play a crucial role. It also offers excellent performance for a wide array of power management applications. The current-sense amplifiers offers features like low offset, high voltage input, low temperature drift, and low input bias current.
The current sensing amplifiers is the best solution for portable PCs, telephones, and other systems where monitoring of battery power-line is critical. In such situation it offers high precision. This factor mainly drives the growth of current-sense amplifiers market. As well as the power controlling capacity of current-sense amplifiers also increase its demand in global market. Furthermore, the high-side current sensing amplifiers eliminates ground disturbance and detects the high load current caused by accidental shorts. Also the current-sense amplifiers provide a high-precision, low offset, high flexibility, and high input voltage solution to maximize reliability and efficiency with a zero-drift architecture which makes these amplifiers more robust across a broad range of applications. These factors increases the adoption of current-sense amplifier in automotive and electronics devices. However, factors such as high cost of high-side current sensing amplifier is likely to hamper the current-sense amplifier market growth.
