Bypass capacitors (C1, C2, C3, C4, C5) should be connected as close to the IC as possible.
The constant current that flows through the H-SW G can be calculated as: Io(const) = Vlimit/R3
In case of using the above application example, Vlimit and IO (const) are calculated as follows:
Vlimit = Vref (= 0.6 V) × R2/(R1 + R2) (= 0.167) = 0.1 V, IO (const) = 0.1 V/RF (= 1 ) = 0.1 A
Note: Excessive power might be introduced into the IC in case of a short-circuit between power supply and ground, an output short-circuit to power supply, an output short-circuit to
ground or a short-circuit across the load. If any of these events occur, the device may therefore be deteriorated or permanently damaged.
