FEATURE DESCRIPTION (CONTINUED)
In each charge mode if time-over occurs charging is prohibited and LED-R blinks. Turning the power off to release UVLO,
battery connection detection, or CHG-SW switching will enable the charge sequence to restart.
NJW4100 incorporates a test mode that shortens the timer block function's test time by 1/150,000.
To operate in test mode set the TH pin voltage to a value no greater than that of the TL pin. In test mode, regardless of the
external timing capacitors C1, C2, the internal timer clock frequency will operate in a range of approximately 200kHz to
300kHz. The following shows calculation values when the oscillating frequency is 250kHz (4
μ
s cycle).

When the TDET pin voltage is approximately 1.2V or greater, the pre-charge / quick charge timers operate normally.
If you want to further reduce the test time, setting TDET pin voltage makes it possible to run each of the timer counters
divided in half. When the TDET pin is approximately 0.3V or less, the first half of the counter is bypassed. When the voltage
is approximately greater than 0.4V and less than 1.1V, the second half of the counter is bypassed.
