6 / 47 page ![]() Block diagram and pin description L99DZ70XP 6/47 Doc ID 15162 Rev 3 1 Block diagram and pin description Figure 1. Block diagram Table 2. Pin definition and functions Pin Symbol Function 1, 18, 19, 36 GND Ground: reference potential. Important: For the capability of driving the full current at the outputs all pins of GND must be externally connected! 2, 35 OUT11 Highside driver output 11. The output is built by a highside switch and is intended for resistive loads, therefore the internal reverse diode from GND to the output is missing. For ESD reason a diode to GND is present, but the energy which can be dissipated is limited. The highside driver is a power DMOS transistor with an internal parasitic reverse diode from the output to VS (bulk-drain-diode). The output is over-current protected. Important: for the capability of driving the full current at the outputs both pins of OUT11 must be externally connected!
