Description

The AAAP(EUBI)+ is a model of electronic component used for the secondary protection of lithium-ion batteries with one to four cells. It incorporates a high precision voltage detector circuit and a delay circuit, making it ideal for use in lithium ion rechargeable battery packs. This component model belongs to the IC chips category and has several features that make it stand out such as internal high-precision voltage detector circuit, high withstand voltage device, wide operating voltage range, and low current consumption. The output logic and form consist of four types, making it highly versatile and adaptable.

Specifications and features

1. Internal high-precision voltage detector circuit:
• Overcharge detection voltage range : 3.70 to 4.50 V : Accuracy of ± 25 mV (at +25 °C) (at a 5 mV/step) Accuracy of ± 50 mV (at -40 to +85 °C)
• Hysteresis : 5 optional models available and selectable: 0.38±0.1 V, 0.25±0.07 V, 0.13±0.04 V, 0.045±0.02 V, None
2. High withstand voltage device: Absolute maximum rating: 26 V
3. Wide operating voltage range: 3.6 V to 24 V (refers to the range in which the delay circuit can operate normally after overvoltage is detected)
4. Delay time during detection: Can be set by an external capacitor.
5. Low current consumption: At 3.5 V for each cell: 3.0 µA max. (+25 °C) At 2.3 V for each cell: 2.4 µA max. (+25 °C)
6. Output logic and form: 4 types — CMOS output active “H”, CMOS output active “L”, Pch open drain output active “L”, Nch open drain output active “H” (only CMOS output for 0.045 V hysteresis models)
7. Lead-free products
