Does this look OK before I commit it to a PCB?
Task is to pull a microprocessor pin low when the Vin voltage is between 5V and 60V.
R4 is just to keep LTspice happy and will not be included.
R1 will be 1/2W all others 1/8W
Q1 is showing 562mW dissipation @ 60Vin (it will actually be a ON semi BCP53 series PNP 1.5A--12mW/degC)... Is that ok???
U1 opto (LiteON corp LTV-816S) is getting approx. 9.3mA @5V and 13.6mA @60V.. Is that ok???
