... One double high-side switch and two low-side switches. The drains of these three vertical DMOS chips are mounted on separated leadframes. The sources are connected to individual pins, so the BTS 7811K can be used in H-bridge- as well as in any other configuration. The double high-side is manufactured in SMART SIPMOS ...

... UVOFF. Open Load Detection The open load detection of the BTS 7811K works in OFF condition and is based on a voltage measurement at the source of the high side switch. In order to use the open load detection a pull up resistor to 5V has to be connected to source of one of the high side switches. Because in ON condition this pull up resistor would connect the bridge output to the µ ...
