ZXCT1009Q数据手册集成电路（IC）的电流调节/管理规格书PDF

描述 Description

The ZXCT1009Q is a micropower high side current sense monitor. This device eliminates the need to disrupt the ground plane when sensing a load current.

\t 

\tIt takes a high side voltage developed across a current shunt resistor and translates it into a proportional output current. A user defined output resistor scales the output current into a ground-referenced voltage.

\t 

\tThe wide input voltage range of 20V down to as low as 2.5V make it suitable for a range of applications. A minimum operating current of just 4μA, combined with a SOT23 package make it a unique solution for portable battery equipment.

\t 

\tThe ZXCT1009Q has been qualified to AEC-Q100 Grade 3 and is Automotive Grade supporting PPAPs.
