TEST CONDITION

RROSC = 41.9kΩ

RROSC = 41.9kΩ

RROSC = 41.9kΩ

-5mA ≤ I(VBIAS) ≤ 0

With FB = 0V, adjust V(SS/DEL) until

EAOUT drives high

Relative to Charge Voltage

RROSC = 41.9kΩ

I(PWRGD) = 4mA

V(PWRGD) = 5.5V

-150mA ≤ I(VCCVID) ≤ 0

I(VCCVID) = -20mA

I(VCCVID) = -150mA

Relative to regulated VCCVID Output

Voltage

Relative to Charge Voltage

I(VIDPGD) = 4mA
