Thermal

shutdown

Note: As long as the voltages applied to VCC, VS1, VS2, and IN1 through IN4 are within the limits set by the absolute

maximum ratings, there are no restrictions on the relationship of each voltage level in comparison

with the others (regarding which is higher or lower). (ex. VCC = 3 V, VS1, 2 = 2 V, IN1 to IN4 = 5 V)

Vcont pin

(= constant)

As shown in the above diagram, the Vcont pin outputs the voltage of the band gap Zener VZ+VF (= 1.93 V).

In normal use, this pin is left open.

The drive current ID is varied by the Vcont voltage. However, because the band gap Zener is shared, it functions as a bridge.

No.3947-3/5
