S-8229A - Battery Monitoring IC S-8229A Series

The S-8229A Series is a battery monitoring IC developed using CMOS technology. Compared with conventional CMOS voltage detectors, the S-8229 Series is ideal for the applications that require high-withstand voltage due to its maximum operation voltage as high as 24 V.
The S-8229 Series is capable of confirming the voltage in stages since it detects three voltage values.

Features

Detection voltage accuracy: ±1.0%
Hysteresis characteristics: V_HYS1 to V_HYS3 = 0 mV, 50 mV, 300 mV, 400 mV, 500 mV
Current consumption: During operation: I_DD1 = 9.0 μA max. (−V_DETtotal^*1 ≥ 42 V) , I_DD1 = 11.0 μA max. (−V_DETtotal^*1 < 42 V); During power-off: I_DD2 = 0.1 μA max.
Operation voltage range: V_DD = 3.6 V to 24 V
Detection voltage: −V_DET1(S) to −V_DET2(S) = 10.5 V to 21.5 V (0.1 V step)
−V_DET3(S) = 7.5 V to 21.5 V (0.1 V step)
Output form: Nch open-drain output
Output logic^*2: Full charge all on, full charge all off
Operation temperature range: Ta = -40°C to +85°C
Lead-free (Sn 100%), halogen-free

*1. −V_DETtotal: Total detection voltage
−V_DETtotal = −V_DET1(S) + −V_DET2(S) + −V_DET3(S)
*2. Full charge all on: When the input voltage is equal to or higher than each of the three detection voltage values,
V_OUT1 = V_OUT2 = V_OUT3 = V_SS.
Full charge all off: When the input voltage is equal to or higher than each of the three detection voltage values,
V_OUT1 = V_OUT2 = V_OUT3 = “High-Z”.

Applications

Rechargeable lithium-ion battery pack
