Product details
Overview
AP9214L-AE-HSBR-7 from Diodes Incorporated is a single-chip Li+ battery protection IC integrating dual N-channel MOSFETs (RSS(ON) ≤16.5 mΩ), overcharge/overdischarge voltage detection (±25 mV accuracy), discharge overcurrent sensing (±15 mV), and short-circuit protection with 1 μs response. It operates in 1-cell Li+ packs for portable power tools, Bluetooth headsets, and medical wearables.
For engineers reviewing the AP9214L-AE-HSBR-7 datasheet, AP9214L-AE-HSBR-7 pinout, AP9214L-AE-HSBR-7 application, or AP9214L-AE-HSBR-7 equivalent, key selection criteria include its U-DFN2535-6 (Type B, Option 2) package, selectable power-down mode, 0V charge enable, and ±25 mV overcharge voltage detection accuracy at +25°C.
Technical Context
The AP9214L-AE-HSBR-7 implements independent analog comparators for VDD–VSS (battery voltage), VM–VSS (discharge current), and VDD–VM (charger voltage), each feeding dedicated delay timers (tCU, tDL, tDOC, tSHORT). Its logic circuit controls two integrated N-MOSFETs via level-shifted gate drivers with common drain (EP pad).
It supports factory-configured options: power-down mode (0.1 µA standby), 0V battery charge enable (V0CHA = 1.2 V), and auto-release overcharge protection. The VM pin interfaces to an external sense resistor (R2 = 2.7 kΩ typical) to monitor bidirectional current flow without external op-amps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Operating Range | 1.5 V to 5.5 V - supports full Li+ cell voltage range (2.5–4.4 V) with margin for transient spikes. |
| Overcharge Detection Voltage | 4.25 V ±25 mV - precise cutoff prevents cell degradation during CC/CV charging phase. |
| Discharge Overcurrent Threshold | 0.100 V ±15 mV - enables use of low-value, high-power sense resistors (e.g., 10 mΩ @ 10 A). |
| Short-Circuit Response Time | 1.0 µs ±40% - shuts off discharge path before PCB trace fusing or thermal runaway initiates. |
| Quiescent Current (Normal) | 3.0 µA typ @ +25°C - extends shelf life of sealed battery packs for >10 years without significant self-discharge. |
| RSS(ON) (Discharge MOSFET) | 13.5 mΩ max @ VDD = 3.9 V - limits I²R loss to <1.4 W at 6 A continuous discharge, enabling compact thermal design. |
| 0V Charge Enable | Yes - allows recovery of deeply depleted cells (0 V) using standard CC/CV chargers without manual pre-charge circuits. |
Pinout & Package
AP9214L-AE-HSBR-7 uses the U-DFN2535-6 (Type B, Option 2) package: 2.5 mm × 3.5 mm × 0.55 mm body with exposed thermal pad (EP). Pin 1 is S1 (discharge MOSFET source); Pin 2 is VSS; Pin 3 is VDD; Pin 4 is VM; Pin 5 is S2; Pin 6 is NC; EP is common drain.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1 (Pin 1) | Source of discharge MOSFET | Connects directly to battery negative terminal; carries full load current; requires low-inductance layout. |
| VSS (Pin 2) | Negative supply reference | Ground return for internal comparators and logic; must be star-connected to S1 to avoid sensing error. |
| VDD (Pin 3) | Positive supply input | Connected to battery positive via R1 (330–470 Ω); filters supply noise and limits reverse-polarity fault current. |
| VM (Pin 4) | Current sense input | Monitors voltage drop across R2 (2.7 kΩ typical) between P− and S2; determines charge/discharge direction and magnitude. |
| S2 (Pin 5) | Source of charge MOSFET | Connects to charger negative input; blocks reverse current when charge MOSFET is off. |
| NC (Pin 6) | No connection | Must remain unconnected and floating; no pull-up/down or routing allowed. |
| EP | Common drain / thermal pad | Electrically tied to both MOSFET drains; requires ≥100 mm² copper pour for thermal dissipation and low-impedance GND tie. |
Key Features
| Feature | Design Value |
|---|---|
| Dual integrated N-MOSFETs | Eliminates external FETs and gate drivers, reducing BOM count by 4 components and PCB area by >30%. |
| Built-in fixed delay timers | Removes need for external RC networks-tCU = 1.0 s, tSHORT = 1.0 µs-ensuring consistent timing across temperature and voltage. |
| Selectable power-down mode | Reduces quiescent current to 0.1 µA max, extending shelf life of unused battery packs without external enable circuitry. |
| Factory-configurable 0V charge | Enables automatic recovery of fully discharged cells using standard chargers, avoiding costly manual pre-charge solutions. |
| Overvoltage charger detection | Monitors VDD–VM up to 10.5 V (±2 V accuracy) to disable charging if faulty or mismatched charger is attached. |

FAQ
What is the function of the VM pin on AP9214L-AE-HSBR-7?
The VM pin senses voltage drop across an external current-sense resistor (R2) between P− and S2. It enables bidirectional current monitoring: positive VM–VSS indicates discharge; negative VM–VSS indicates charge. Internal RVMS and RVMD resistors provide automatic pull-down/pull-up during fault states to ensure reliable MOSFET control without external biasing.
Does AP9214L-AE-HSBR-7 support overvoltage protection for the charger input?
Yes. The device monitors VDD–VM voltage and triggers overvoltage charger protection at 8.0 V (±2 V) to disable the charge MOSFET. Release occurs at 7.3 V (±2 V). This function operates without delay and protects against damaged or incompatible chargers supplying >6 V to the battery pack.
How does the power-down mode affect recovery from overdischarge?
In power-down mode (enabled on AP9214L-AE-HSBR-7), the IC enters deep sleep (<0.1 µA) upon overdischarge. Recovery requires external charging: only when charger voltage raises VDD above VDU (e.g., 2.8 V) while VM is pulled low by R2 does the device exit power-down and resume normal operation.
Can AP9214L-AE-HSBR-7 be used with lithium iron phosphate (LiFePO₄) cells?
No. The AP9214L-AE-HSBR-7 is calibrated for Li+ chemistry with overcharge detection range 3.5–4.5 V and overdischarge range 2.0–3.4 V. LiFePO₄ cells require 3.65 V overcharge and 2.0 V overdischarge thresholds with different hysteresis-using this IC would cause premature cutoff or unsafe operation.
