Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- 1.3 DW01HA-DS-13_EN JAN 2014 Datasheet DW01HA One Cell Lithium-ion/Polymer Battery Protection IC With Built-in MOSFET FORTUNE' Properties For Reference Only Fortune Semiconductor Corporation 富晶電子股份有限公司 23F,No.29-5, Sec.
- The accurate ±25mV overcharging detection voltage ensures safe and full utilization charging.
- z Protection IC： Ultra-Low Quiescent Current at 2.5μA (Vcc=3.9V). Ultra-Low Overdischarge Current at 1.8μA (Vcc=2.0V). Overcharge Protection Voltage 4.28V ± 25mV Overdischarge Protection Voltage 2.4V ± 100mV Overcurrent Protectio.
- 100~470Ω Resistance should be as small as possible to avoid lowering of the overcharge detection accuracy caused by VDD pin current.
- Use 470Ω for better ESD protection.
- 0.1μF R2 Protection for reverse connection of a charger.
- 1k~2kΩ Select a resistance as large as possible to prevent large current when a charge is connected in reverse.
Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
