24V Protected High-Side Switch BTT6020-1ERA
Application Example With Inductive/Resistive/Capacitive Load

Thermal model description:
THERMAL_MODEL = 1: 10W 85C 1s0p footprint
THERMAL_MODEL = 2: 10W 85C 1s0p 300mm2 cooling area
THERMAL_MODEL = 3: 10W 85C 1s0p 600mm2 cooling area
THERMAL_MODEL = 4: 10W 85C 2s2p

This example circuit demonstrate the application example for the BTT6020-1ERA, one of the
PROFET™+ 24V devices. Infineon’s PROFET™+ 24V protected high-side switches drive
resistive, capacitive as well as inductive loads (e.g. truck bulbs, car bulbs, valves, motors,
relays, capacitors, LEDs…). The power switch is controlled via the IN pin. The switching
frequency can be adjusted in the green text box on the left side.

The PROFET™+ 24V devices also provide a sense current at the IS pin, which can be enabled
via the DEN (Diagnosis ENable) pin. The sense signal (IS) can be connected to an ADC channel
for monitoring and controlling. The current sense ratio k_ILIS is dependent on the sense resistor
R_IS, please refer to datasheet section 7.3.
