TWO PHASE HALL EFFECT LATCH WITH LOCKED PROTECTION

AH287

Typical Application (Note 3)

Note 3:

Due to the special internal circuit of AH287, the minimum operation voltage of lock protection and

automatic restart is higher than the minimum startup voltage. It is 4.5V.

2. The capacitances of C

CT

and C2 are adjustable base on system requirements. The recommended values

are as below:

1.

C

CT

1µF/9V~2.2µF/9V

C2

1µF/50V~2.2µF/50V
