14 / 162 page  Block diagram and pin descriptions L99DZ120 14/162 DocID029145 Rev 4 7 NC Not connected 8 NC Not connected 9 OUT14 High-side-driver output to drive LEDs 10 OUT13 High-side-driver output to drive LEDs 11 OUT12 High-side-driver output to drive LEDs 12 OUT9 High-side-driver output to drive LEDs 13 OUT10 High-side-driver-output 14 OUT11 High-side-driver output to drive LEDs 15 LS1_FSO Fail Safe low-side switch (Active low) 16 LS2_FSO Fail Safe low-side switch (Active low) 17 VS Power supply voltage for power stage outputs (external reverse battery protection required), for this input a ceramic capacitor as close as possible to GND is recommended. Important: For the capability of driving, the full current at the outputs all pins of VS must be connected externally! 18 VS; 2nd pin Current capability (pin description see above) 19 OUT7 High-side-driver output to drive LEDs or a 10 Watt bulb (programmable Rdson) 20 OUT6 Half-bridge outputs: the output is built by a high-side and a low-side switch which are internally connected. The output stage of both switches is a power DMOS transistor. Each driver has an internal parasitic reverse diode (bulk-drain-diode: high-side driver from output to VS, low-side driver from GND to output) 21 OUT1 Half-bridge outputs: the output is built by a high-side and a low-side switch which are internally connected. The output stage of both switches is a power DMOS transistor. Each driver has an internal parasitic reverse diode (bulk-drain-diode: high-side driver from output to VS, low-side driver from GND to output) 22 NC Not connected 23 OUT5 Half-bridge outputs: the output is built by a high-side and a low-side switch which are internally connected. The output stage of both switches is a power DMOS transistor. Each driver has an internal parasitic reverse diode (bulk-drain-diode: high-side driver from output to VS, low-side driver from GND to output) 24 OUT5; 2nd pin Current capability (pin description see above) 25 VSREG Power supply voltage to supply the internal voltage regulators, OUT15 and the OUT_HS (external reverse battery protection required / Diode) for this input a ceramic capacitor as close as possible to GND and an electrolytic back up capacitor is recommended. 26 OUT_HS High-side-driver output to drive LEDs or to supply contacts Table 1.
