8.4.3 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 8-3 shows the timing for the Customer Test Mode.

Figure 8-4 shows the measurement for current consumption for the product for both VDD and Vx.
