21 / 24 page  21/24 AN1596 - APPLICATION NOTE APPENDIX Symptom Component Schematic Notes 1) Input and Status pins R1, R2, Rpu R1, R2 and Rpu chosen in order to limit the control pins currents to 10mA. R1 and R2 must protect the microcontroller against the latch-up (see point 6, 7). 2) Off-State open load detection in digital HSDs (case 1) Rpu Choose Rpu in order not to have false open load detection: VOUT=(Vpu/(RL+Rpu))• RL<VOLmin Choose Rpu to assure detection when load is disconnected: Rpu<(Vpu–VOLmax)/IL(off2) VOLmin, VOLmax, IL(off2) are given in datasheets. 3) Off-State open load detection in digital HSDs (case 2) Rpu, R1, R2, T1, T2 To minimize power consumption, the microcontroller can periodically switch on T1 and T2 when the ignition key is inserted.
