 Description

The DIO221X series is a high-side current-sense

amplifier with voltage output and can sense drops

across shunts at common-mode voltage from -0.1 V

to 75 V. The choices of gain are 20 V/V, 50 V/V, and

100 V/V, with the according bandwidths of 440 kHz,

110 kHz, and 65 kHz.

The DIO221X series is integrated with an open-drain

comparator and internal reference at 0.6 V voltage.

By pulling or grounding the pin, the comparator can

be made transparent or latched as needed.

The DIO221X series operates from single 3 V to 40 V

supply under -40°C to 125°C, with a maximum supply

current of 620 μA.
