Product details
Overview
AP9214L-AI-HSB-7 from Diodes Incorporated is a single-chip Li+ battery protection IC integrating dual N-channel MOSFETs (RSS(ON) = 13 mΩ typ at VDD = 4.0 V) and precision voltage/current detection circuitry for 1-cell rechargeable battery packs. It delivers overcharge (3.5–4.5 V, ±25 mV), overdischarge (2.0–3.4 V, ±35 mV), discharge/charge overcurrent (±15 mV), and short-circuit (±100 mV) protection with fixed delay timing and 0V charge enable functionality.
For engineers reviewing the AP9214L-AI-HSB-7 datasheet, AP9214L-AI-HSB-7 pinout, AP9214L-AI-HSB-7 application in Li+ battery packs, or AP9214L-AI-HSB-7 equivalent for portable power management, this device supports high-accuracy, low-quiescent-current (3.0 µA typ) protection with selectable power-down mode and factory-configured overcharge auto-release behavior.
Technical Context
The AP9214L-AI-HSB-7 implements a dual-MOSFET protection architecture with common-drain EP pad, using internal level-shifted logic to independently control charging (S2→VM path) and discharging (S1→VM path) MOSFETs. Its detection circuitry operates across VDD = 1.5–5.5 V and supports -40°C to +85°C ambient operation.
It features programmable thresholds via factory trimming - including overcharge hysteresis (0.1–0.4 V), overdischarge hysteresis (0–0.7 V), and built-in 0V battery charge enable - all validated per Diodes' DS38413 Rev. 4-3 specification. The device uses high-voltage CMOS process (VDD–VM up to 30 V) and includes integrated RVMD/RVMS pull-up/pull-down resistors (300 kΩ / 30 kΩ typ) for VM-sense biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 1.5 V to 5.5 V - supports full Li+ cell voltage range (2.5–4.4 V) plus margin for transient spikes |
| IQ (Normal Mode) | 3.0 µA typ - enables >1-year shelf life for battery-powered IoT devices without periodic wake-up |
| RSS(ON) | 13 mΩ typ (VDD = 4.0 V) - limits conduction loss to <130 mW at 1 A continuous discharge current |
| VCUR Accuracy | ±25 mV - ensures reliable overcharge cutoff within ±0.6% of 4.2 V nominal, preventing cell degradation |
| tSHORT | 1.0 µs typ - detects hard shorts before PCB traces or cells sustain thermal damage |
| VOVCHG | 8.0 V ±2 V - protects against faulty >5 V chargers by disabling charge path before external FET failure |
| 0V Charge Enable | Factory-set active - allows recovery of deeply discharged cells without manual pre-charge circuitry |
Pinout & Package
AP9214L-AI-HSB-7 is housed in a U-DFN2535-6 (Type B) thermally enhanced package with exposed drain pad (EP), optimized for compact battery pack layouts and efficient heat dissipation during high-current events.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1 | Discharge MOSFET source | Connects directly to battery negative terminal; carries full load current during discharge |
| VSS | Negative supply reference | System ground return for all internal comparators and logic; must be low-impedance |
| VDD | Positive supply input | Connected to battery positive via R1 (330–470 Ω); powers internal circuitry and gate drivers |
| VM | Current sense and charger monitor node | Monitors voltage drop across R2 (2.7 kΩ typical) to detect charge/discharge current and charger presence |
| S2 | Charge MOSFET source | Connects to charger negative input; isolates charger when overvoltage or overcurrent detected |
| NC | No-connect terminal | Pin 5 in Option 1 layout - must remain floating; no internal connection or function |
| EP | Common drain thermal pad | Shared drain node for both MOSFETs; requires large copper pour for thermal stability under 9 A peak |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-Channel MOSFET Integration | Eliminates need for external back-to-back FETs and gate drive components, reducing BOM count by ≥4 parts |
| Programmable Overcharge Hysteresis | 0.1–0.4 V range with 50 mV steps enables stable re-enable after transient overvoltage without oscillation |
| Fixed Detection Delay Timing | ±20% accuracy at +25°C avoids external RC timing networks, improving production consistency |
| Power-Down Mode Selectable | Reduces quiescent current to ≤0.1 µA in overdischarge state, extending shelf life for sealed battery modules |
| Overvoltage Charger Detection | 8.0 V fixed threshold disables charging path before external charger IC or cable fault damages cell |
Applications
| Power Tool Battery Packs | Wireless Headphone Charging Cases |
|---|---|
|
Use Scenario: 18 V nominal (5S) power tool packs with fast-charge capability and high pulse discharge currents up to 30 A. IC Role / Device Role / Timing Role: Primary protection controller monitoring cell voltage, pack current, and charger input; executes sub-millisecond short-circuit shutdown. Use Value: Prevents thermal runaway during motor stall events by detecting 0.45–0.7 V short-sense threshold within 1 µs, enabling safe mechanical fuse elimination. |
Use Scenario: Compact Bluetooth earbud cases with integrated 3.7 V Li+ cell and USB-C charging, requiring ultra-low standby current. IC Role / Device Role / Timing Role: Single-chip protector managing charge enable, overdischarge release, and 0V recovery without external supervisor IC. Use Value: Enables 3.0 µA normal-mode IQ and 0.1 µA power-down current, supporting >18-month shelf life with factory-set 0V charge enable. |
| Medical Wearable Monitors | Smart Home Sensor Nodes |
|
Use Scenario: FDA-classified wearable ECG patches with sealed Li+ battery and multi-year operational lifetime requirement. IC Role / Device Role / Timing Role: Safety-critical protector enforcing ±35 mV overdischarge detection accuracy and latch-mode overcharge response. Use Value: Guarantees cell voltage remains ≥2.0 V during storage, preserving electrode integrity and calibration stability over 5-year shelf life. |
Use Scenario: Zigbee/Z-Wave battery nodes deployed in inaccessible locations (e.g., HVAC ducts), requiring field-replaceable but non-serviceable batteries. IC Role / Device Role / Timing Role: Autonomous protector with auto-wake-up on voltage rise, eliminating need for manual reset after deep discharge. Use Value: Recovers from 0 V without external intervention using factory-set V0CHA = 1.2 V trigger, avoiding firmware-level battery management complexity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Li+ battery protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Seiko Instruments S-8261A | Separate protection IC + external MOSFETs; no integrated FETs; higher BOM cost and board area | Lacks 0V charge enable and overvoltage charger detection; requires external timing capacitors | Choose when discrete FET selection (e.g., ultra-low RDS(on) or high-temp rating) is mandatory |
| Ricoh RP506K | Single-chip solution with integrated MOSFETs but only 20 mΩ RSS(ON); no overvoltage charger detection | Supports auto-release overcharge but lacks factory-programmable hysteresis steps | Choose for cost-sensitive consumer electronics where 13 mΩ vs. 20 mΩ conduction loss is not critical |
Compared with S-8261A and RP506K, AP9214L-AI-HSB-7 uniquely combines ultra-low RSS(ON), integrated overvoltage charger monitoring, and factory-configurable 0V charge enable - delivering lower system-level power loss, enhanced safety margin, and reduced design validation effort for sealed battery modules.

FAQ
What is the function of the NC pin on AP9214L-AI-HSB-7?
Pin 5 is designated NC (No Connect) in the U-DFN2535-6 (Type B) Option 1 pinout and must remain unconnected and floating. It has no internal electrical connection or function - routing a trace or solder mask opening to this pin may cause unintended coupling or ESD susceptibility.
Does AP9214L-AI-HSB-7 support automatic recovery from overdischarge without a charger?
No - AP9214L-AI-HSB-7 uses power-down mode (indicated by "AI" suffix), meaning it enters ultra-low-current sleep (<0.1 µA) upon overdischarge and requires charger connection to restore normal operation. Auto-wake-up behavior is exclusive to AP9214LA variants.
How is the 0V battery charge function enabled on this part?
The 0V charge function is factory-trimmed and permanently enabled in AP9214L-AI-HSB-7 (per ordering code "AI"). It allows charging initiation when battery voltage is 0 V, using internal V0CHA = 1.2 V threshold - no external configuration or resistor network is required.
What is the maximum continuous discharge current supported by AP9214L-AI-HSB-7?
At TA = +25°C, the device supports 9.0 A continuous drain current with VGS = 4.5 V. At +70°C, derating applies to 7.1 A. Thermal performance depends on PCB copper area under the EP pad; ≥200 mm² of 2-oz copper is recommended for sustained 7 A operation.
