1 / 17 page AP9211 Document number: DS37596 Rev. 2 - 2 1 of 17 www.diodes.com December 2015 © Diodes Incorporated AP9211 SINGLE CHIP SOLUTION FOR 1-CELL Li+ BATTERY PACK Description The AP9211 is a single chip protection solution specially designed for 1-cell Li+ rechargeable battery pack application. The AP9211 includes a 1-cell Lithium ion battery protection chip and dual N-CHANNEL MOSFET with common drain. The AP9211 provides rich battery protection features and can turn-off the N-CHANNEL MOSFET by detecting overcharge voltage/current, over discharge voltage/current, or load short circuit. AP9211 has built- in fixed delay time to save external components. The AP9211 is available in U-DFN2030-6 package. Features High Voltage CMOS Process, up to 30V (VDD to VM) Low Quiescent Current (+25°C ) In Normal Mode, 3.0µA (Typ.), 4.5µA (Max.) VDD = 3.5V In Power-Down Mode, 0.1µA (Max.) High-Accuracy Voltage Detection Circuit (+25°C) Overcharge Detection Voltage: 3.5V to 4.5V (5mV Steps) Accuracy ±25mV Overcharge Hysteresis Voltage Range: 0.1V to 0.4V (50mV Steps) Accuracy ±50mV Overdischarge Detection Voltage: 2.0V to 3.4V (10mV Steps) Accuracy ±35mV Overdischarge Hysteresis Voltage Range: 0V to 0.7V (40mV Steps) Accuracy ±65mV Discharge Overcurrent Detection Voltage: 0.05V to 0.32V (10mV Steps) Accuracy ±15mV Short Current Detection Voltage: 0.45V to 0.7V (50mV Steps) Accuracy ±100mV Charge Overcurrent Detection Voltage: -0.2V to -0.05V (10mV Steps) Accuracy ±15mV Overcharger Detection Voltage: 8.0V (Fixed) Accuracy ±2V Overcharger Release Voltage: 7.3V (Fixed) Accuracy ±2V Built-in Fixed Detection Delay Time (+25°C ), Accuracy ±20% Power-Down Mode Selectable (Yes or No) 0V Battery Charge Selectable (Permission or Inhibition) Overcharge Protection Mode Selectable (Auto Release or Latch) Totally Lead-free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) Pin Assignments (Top View) 1 2 3 5 4 S1 VSS VDD VM S2 NC 6 EP U-DFN2030-6 Applications Li+ Rechargeable Battery Pack Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony- free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds. |
