Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX49921TATA/VY is a high-precision, unidirectional current detection amplifier (CSA) with an operating input common-mode range of 0 to +70V, but provides input common-mode voltage protection down to -42V and up to +80V to prevent battery backgrounding and high voltage spikes. The MAX49921 is suitable for current monitoring of inductive loads, such as DC motors and solenoid valves, where the common-mode voltage can become negative due to inductive recoil, battery backgrounding, or transient events.
