• Manufacturer Part Number: s-8204bad-tct1g
• Description: Battery Protection Ic For 3-series Or 4-series Cell Pack
• Manufacturer: Seiko Instruments Inc.

Rev.1.3
8. CTLC and CTLD Pins
The S-8204B Series has two pins to control. The CTLC pin controls the output voltage from the COP pin, the CTLD
pin controls the output voltage from the DOP pin. Thus it is possible for users to control the output voltages from the
COP pin and DOP pin independently. These controls precede the battery protection circuit.
Caution
_00
Note that when the power supply fluctuates, unexpected behavior might occur if an electrical
potential is generated between the potentials of “H” level input to the CTLC/CTLD pins and IC’s
