Description

This design uses a single Dialog GreenPAK SLG46110 to realize a low-side sensing over current detection circuit with a latching output used to enable/disable an external high-side PMOS load switch. By configuring one of the onboard comparators (ACMP1) to perform as a Non-Inverting Amplifier with a gain of 22.5, we can use a very small 0.010 ohm low-side sense resistor to, in this case, detect a 4A maximum current.
