Device Functional Modes (continued)

8.4.3 Customer Test Mode

Customer Test Mode (CTM) helps to reduce test time for checking the overvoltage delay timer parameter once

the circuit is implemented in the battery pack. To enter CTM, VDD should be set to at least 10 V higher than V3

(see Figure 7). The delay timer is greater than 10 ms, but considerably shorter than the timer delay in normal

operation. To exit CTM, remove the VDD to VC3 voltage differential of 10 V so that the decrease in this value

automatically causes an exit.

CAUTION

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

into CTM. Also avoid exceeding Absolute Maximum Voltages for the individual cell

voltages (V3–V2), (V2–V1), and (V1–VSS). Stressing the pins beyond the rated limits

may cause permanent damage to the device.

Figure 7 shows the timing for CTM.

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