VOLTAGE MONITORING IC WITH CELL BALANCING FUNCTION
Rev.1.4_00
S-8249 Series
13
5. DP pin
The S-8249 Series has the DP pin (Test mode switching pin). The S-8249 Series is set to test mode (used to
shorten the delay time) by inputting a voltage of VDPH or higher to the DP pin.
Table 13
DP Pin
Status
Open (VDP = VSS)
Normal operation mode
"H" (VDP
≥ VDPH)
Test mode
"L" (VDP
≤ VDPL)
Normal operation mode
In test mode, the cell balancing detection delay time (tBU) and overcharge detection delay time (tCU) are
shortened to 1/64 of the delay time in the normal operation mode.
The DP pin is pulled down to VSS by the internal resistor. When in a mode other than test mode, leave the DP
pin open or short it with VSS.
