SPF7302 Note:Original and new
Description
The SPF7302 is a fully protected, single chip full-bridge driver IC for DC brush motor applications. The various protection circuits integrated are: overvoltage protection (OVP); overcurrent protection (OCP) with latch, which is adapted to the DMOSFETs in each full bridge; undervoltage lockout (UVLO); open load detection; and overcurrent limitation.
The package is a thermally enhanced 16-pin HSOP power package with an exposed thermal pad on the bottom side of the package.
