The subcircuit above can be substituted into any of the ProSLIC solutions as an optional bias circuit for Q5, Q6. For
this optional subcircuit, C7 and C8 are different in voltage and capacitance to the standard circuit. R23 and R24 are
additional components.

R28
1/10 W, 1% resistor
For VDD = 3.3 V: 26.1 k
For VDD = 5.0 V: 37.4 k
R28 = (VDD + VBE)/148 A
where VBE is the nominal VBE for Q9
R29
1/10 W, 1% resistor
For VCLAMP = 80 V: 541 k
For VCLAMP = 85 V: 574 k
For VCLAMP = 100 V: 676 k
R29 = VCLAMP/148 A
where VCLAMP is the clamping voltage for VBAT
