Si8540 Datasheet (Silicon Laboratories) - HIGH-SIDE CURRENT SENSE AMPLIFIER

Si8540, HIGH-SIDE CURRENT SENSE AMPLIFIER

The Si8540 is a unidirectional, 36 V (max), high-side current sense amplifier for use in applications requiring current monitoring and/or control.

This device draws bias current from the high-side line to which it is attached, eliminating the need for an external supply.

It measures current from 0.
