Hey everyone! Continuing from our last post about Siproin's SSP8023A driver chip, today we're diving into the SSP8023D.​

The SSP8023D is also a bidirectional relay drive circuit. Just like the SSP8023, it is designed to control DC motors and magnetic latching relays. It can be widely used in smart meters and other pulse and level control applications.

Compared to SSP8023A, the main difference lies in the high-to-low level conversion threshold of the input. The input high and low conversion levels of SSP8023D are around 1.5V, and it is compatible with various microcontrollers.

In terms of packaging, the SSP8023D offers two types: SOP8 and SOP23-6.

If you are working on a project that requires reliable and efficient relay drivers, then SSP8023D is your ideal choice. Please keep an eye on the latest product updates from Siproin.
