BATTERY PROTECTION IC FOR 1-SERIAL TO 4-SERIAL-CELL PACK (SECONDARY PROTECTION)
Rev.3.3
_00
S-8244 Series
(7)
Test Condition 7, Test Circuit 4
Conditions:
•
Set switch 1 to OFF and switch 2 to ON.
Definitions:
•
Set V1, V2, V3 and V4 to 4.6 V and gradually decrease V6 from V
CC
(for CMOS output active “H”
models).
V6 voltage is defined as V
CO (H)
when I2 (= -10
µA)
flows.
•
Set V1, V2, V3 and V4 to 3.5 V and gradually decrease V6 from V
CC
(for CMOS output active “L” or
Pch open drain models).
V6 voltage is defined as V
CO (H)
when I2 (= -10
µA)
flows.
•
Set V1, V2, V3 and V4 to 4.6 V and gradually increase V6 from 0 V (for CMOS output active “L”
models).
V6 voltage is defined as V
CO (L)
when I2 (= 10
µA)
flows.
•
Set V1, V2, V3 and V4 to 3.5 V and gradually increase V6 from 0 V (for CMOS output active “H” or
Nch open drain models).
V6 voltage is defined as V
CO (L)
when I2 (= 10
µA)
flows.
