5 / 172 page  Pin Name Function 7 EI6 Input pin for static or cyclic monitoring of external contacts 8 EI7 Input pin for static or cyclic monitoring of external contacts 9 EI8 Input pin for static or cyclic monitoring of external contacts 10 EI9 Input pin for static or cyclic monitoring of external contacts 11 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! 12 HB1 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). The channel is protected by auto-recovery feature. 13 VS; 2nd pin Current capability (pin description see above) 14 VS; 3rd pin Current capability (pin description see above) 15 HB6 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). The channel is protected by auto-recovery feature. 16 HB21 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). The channel is protected by auto-recovery feature. 17 VS; 4th pin Current capability (pin description see above) 18 NC Not connected 19 HS8 High-side driver output to drive LEDs. The channel is protected by auto-recovery feature. 20 HS17 High-side driver output to drive LEDs 21 VS; 5th pin Current capability (pin description see above) 22 HS16 High-side driver output to drive LEDs 23 HB2 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). The channel is protected by auto-recovery feature. 24 NC Not connected 25 NC Not connected 26 VS; 6th pin Current capability (pin description see above) 27 HS7 High-side driver output to drive LEDs or a 10 W bulb (programmable Rdson). The channel is protected by auto- recovery feature. 28 VS; 7th pin Current capability (pin description see above) 29 HS11 High-side driver output to drive LEDs 30 HS12 High-side driver output to drive LEDs 31 HS13 High-side driver output to drive LEDs 32 HS14 High-side driver output to drive LEDs 33 VS; 8th pin Current capability (pin description see above) 34 VS; 9th pin Current capability (pin description see above) 35 HB5 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). The channel is protected by auto-recovery feature.
