Application Information
Table 8 Bill of Material
Reference Value
Purpose
R_INPUT
10 kΩ
Protection of the µC during overvoltage and reverse battery condition
R_SENSE
10 kΩ
Protection of the µC during overvoltage and reverse battery condition
R_IS
1 kΩ
Sense resistor. Shunt resistor for measuring I_IS by the µC’s AD converter.
C_VS
470µF
Capacitor buffering the supply voltage
Switching an inductive load
D₁
Freewheeling diode for commutation of load current. Depending on load current
and thermal boundary conditions, it may be necessary to use active freewheeling
by a MOSFET, instead of the diode.
External circuitry supporting open load at OFF detection
