CUSTOMER TEST MODE

It is possible to reduce test time for checking the overvoltage function by simply shorting the external CD

capacitor to VSS. In this case, the OV delay would be reduced to the t(CHGDELAY) value, which has a maximum of

170 ms.

CAUTION

Avoid exceeding any Absolute Maximum Voltages on any pins when placing the part

into Customer Test Mode. Also avoid exceeding Absolute Maximum Voltages for the

individual cell voltages (V4–V3), (V3–V2), (V2–V1), and (V1–VSS). Stressing the pins

beyond the rated limits may cause permanent damage to the device.

Figure 13 shows the timing for the Customer Test Mode.
