Product details
Overview
AP9214LA-AI-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 1.2 µs response. It operates in 1-cell Li-ion packs for portable power tools, medical devices, and Bluetooth headsets.
For engineers reviewing the AP9214LA-AI-HSBR-7 datasheet, AP9214LA-AI-HSBR-7 pinout, AP9214LA-AI-HSBR-7 application, or AP9214LA-AI-HSBR-7 equivalent, key selection criteria include its U-DFN2535-6 (Type B, Option 2) package, selectable auto-wake-up mode, 0V charge enable function, and ±100 mV short-detection voltage tolerance under temperature variation.
Technical Context
The AP9214LA-AI-HSBR-7 implements independent analog comparators for VDD–VSS (battery voltage), VM–VSS (discharge current), and VDD–VM (charger voltage), each feeding into logic-controlled delay timers (tCU, tDL, tDOC, tSHORT). Its dual-MOSFET architecture uses common-drain EP pad with separate S1 (discharge source) and S2 (charge source) terminals.
It supports three configurable functions: 0V battery charge permission (factory-set), auto-wake-up on overdischarge recovery (no charger required), and overcharge release behavior (latch vs. auto-release). Internal RVMD/RVMS resistors (300 kΩ typ) enable VM-sense biasing without external components.
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 V–4.4 V) with margin for transient spikes. |
| Overcharge Detection Voltage | 4.25 V ±25 mV - factory-trimmed threshold enabling precise cell voltage cutoff before degradation. |
| Discharge Overcurrent Threshold | 0.15 V ±15 mV - sets 15 A trip point with 10 mΩ sense resistance, suitable for high-current portable tools. |
| Short-Circuit Response Time | 1.2 µs typical - enables sub-microsecond shutdown to prevent thermal runaway during hard shorts. |
| Quiescent Current (Normal) | 3.0 µA typ at +25°C - extends shelf life of sealed battery packs with minimal self-discharge impact. |
| MOSFET RSS(ON) | 13.5 mΩ max at VDD = 3.9 V - limits conduction loss to <200 mW at 9 A continuous discharge. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and medical environments without derating. |
Pinout & Package
AP9214LA-AI-HSBR-7 uses the U-DFN2535-6 (Type B, Option 2) package: 2.5 mm × 3.5 mm × 0.55 mm body, exposed thermal pad (EP), wettable flank leads, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S1) | Discharge MOSFET Source | Connects directly to battery negative terminal; carries full load current during discharge. |
| 2 (VSS) | Negative Power Supply Reference | Ground reference for all internal comparators and logic; must be low-impedance return path. |
| 3 (VDD) | Battery Positive Input | Supplies IC core and gate drivers; connected via R1 (330–470 Ω) to limit inrush and reverse-polarity fault current. |
| 4 (VM) | Charge/Discharge Current Sense Input | Monitors voltage drop across R2 (2.7 kΩ typical) between P− and battery negative to detect charge/discharge direction and magnitude. |
| 5 (S2) | Charge MOSFET Source | Connects to charger negative input; isolates charging path when VCOC or VOVCHG thresholds are exceeded. |
| 6 (NC) | No Connect | Pin left floating per design; no internal connection or function. |
| EP | Common Drain Thermal Pad | Electrically tied to both MOSFET drains; requires large PCB copper pour for thermal dissipation and low-inductance switching. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Dual N-Channel MOSFETs | Eliminates discrete FET layout complexity and reduces board area by >40% versus discrete solutions. |
| Factory-Configured Auto-Wake-Up Mode | Enables automatic recovery from overdischarge without external charger, critical for unattended medical sensors. |
| 0V Battery Charge Enable | Allows safe reactivation of deeply discharged cells (0 V) using standard CC/CV chargers, extending pack service life. |
| Fixed Delay Timers with ±20% Accuracy | Removes need for external RC timing components, improving production yield and long-term reliability. |
| Overvoltage Charger Detection (8.0 V) | Protects against faulty or mismatched chargers in multi-bay docking stations, preventing thermal damage. |
Applications
| Power Tools | Medical Wearables |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 1-cell Li+ battery protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Seiko Instruments S-8261AAB-M6T1U | Single-MOSFET architecture; no integrated charge MOSFET; requires external P-FET for charge path control. | Lacks 0V charge and auto-wake-up; limited to basic protection where charger presence is guaranteed. | Select only if cost sensitivity outweighs functional completeness and system-level integration benefits. |
| Ricoh RP506K001B-TR-F | Higher quiescent current (6 µA typ); no overvoltage charger detection; fixed overcharge hysteresis (0.25 V). | Suitable for consumer wearables but not industrial tools due to reduced short-circuit speed (5 µs) and thermal margin. | Prefer when supply chain diversification is required and design tolerates longer fault-clearing latency. |
Compared with S-8261AAB-M6T1U and RP506K001B-TR-F, the AP9214LA-AI-HSBR-7 delivers superior integration (dual MOSFETs), faster fault response (1.2 µs vs. ≥5 µs), and field-deployable features (0V charge, auto-wake-up), reducing BOM count and qualification effort for ruggedized applications.

FAQ
What is the function of the NC pin (Pin 5) in AP9214LA-AI-HSBR-7?
Pin 5 is designated NC (No Connect) in the U-DFN2535-6 (Type B, Option 2) configuration and has no internal electrical connection. It must remain unconnected and floating on the PCB layout-soldering or routing to any net may cause functional malfunction or ESD vulnerability.
Does AP9214LA-AI-HSBR-7 support overvoltage protection on the charger input?
Yes. The device monitors VDD–VM voltage and triggers charging MOSFET shutdown when it exceeds 8.0 V (±2 V), with automatic re-enable at 7.3 V. This protects against damaged or misconfigured chargers without requiring external components or delay programming.
How does the auto-wake-up mode differ from power-down mode in this part?
Auto-wake-up (enabled in AP9214LA) allows recovery from overdischarge when battery voltage rises above VDU, even without charger connection. Power-down mode (AP9214L) requires charger application to exit overdischarge-this part is factory-configured for auto-wake-up, confirmed by the "A" suffix in the part number.
Can AP9214LA-AI-HSBR-7 be used with 2-cell Li+ configurations?
No. The device is strictly rated for 1-cell operation (VDD–VSS ≤5.5 V absolute max). Applying 2-cell voltage (up to 8.4 V) exceeds its 12 V VDS rating and will cause permanent damage. For 2-cell packs, use Diodes' AP9221 or equivalent dual-cell controllers.
