Product details
Overview
AP9214L-AN-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 at +25°C), discharge overcurrent sensing (±15 mV), and short-circuit protection with 1.4 µs typical response. It operates in 1-cell Li+ packs for portable power tools, Bluetooth headsets, and medical wearables.
For engineers reviewing the AP9214L-AN-HSBR-7 datasheet, AP9214L-AN-HSBR-7 pinout, AP9214L-AN-HSBR-7 application, or AP9214L-AN-HSBR-7 equivalent, key selection criteria include selectable power-down mode, 0V battery charge enable, auto-release vs latch overcharge behavior, and U-DFN2535-6 (Type B, Option 2) package compatibility with thermal pad grounding.
Technical Context
The AP9214L-AN-HSBR-7 implements independent analog comparators for VDD–VSS (cell voltage), VM–VSS (discharge current), and VDD–VM (charge voltage), each feeding into logic-controlled delay timers with ±20% accuracy. Its dual-MOSFET architecture uses common-drain EP pad for shared thermal path and current routing.
Protection decisions are latched or auto-released based on factory configuration; overvoltage charger detection (8.0 V ±2 V) operates without delay, while discharge overcurrent triggers within 1.4 µs. The device supports 0V battery charging via internal threshold (1.2 V start, ≤0.45 V inhibit) and offers two pin-out variants-this part uses HSBR (Option 2: Pin 4 = VM, Pin 5 = NC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Operating Range | 1.5 V to 5.5 V - supports full Li+ cell voltage range including deep discharge recovery. |
| Overcharge Detection Voltage | 4.250 V ±25 mV - factory-set high-accuracy threshold prevents cell damage during CC/CV charging. |
| Discharge Overcurrent Threshold | 0.100 V ±15 mV - enables precise current limiting using external sense resistor (e.g., 10 mΩ → 10 A trip). |
| RSS(ON) Max (Discharge Path) | 16.5 mΩ @ VDD = 3.0 V - minimizes power loss and heat generation under 9 A continuous load. |
| Quiescent Current (Normal) | 3.0 µA typ @ +25°C - extends shelf life of dormant battery packs without compromising responsiveness. |
| Short-Circuit Response Time | 1.4 µs typ - protects against catastrophic failure during accidental terminal shorts. |
| 0V Charge Enable | Enabled - allows safe reactivation of deeply discharged cells (e.g., after long-term storage). |
| Power-Down Mode | Disabled (Auto-Wake-Up) - maintains monitoring capability during overdischarge, enabling self-recovery when voltage rises. |
Pinout & Package
AP9214L-AN-HSBR-7 uses the U-DFN2535-6 (Type B) package with exposed thermal pad (EP), optimized for low-profile battery pack integration. Pin-out Option 2 places VM on Pin 4 and leaves Pin 5 unconnected (NC), requiring PCB layout alignment with this configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1 | Source of discharging MOSFET | Connects directly to battery negative; carries full load current during discharge. |
| VSS | Negative supply reference | Ground return for all internal comparators and logic; must be low-impedance. |
| VDD | Positive supply input | Connected to battery positive through current-limiting resistor R1 (330–470 Ω); powers IC core. |
| VM | Charge/discharge current sense node | Monitors voltage drop across R2 (2.7 kΩ typical) to detect charge/discharge direction and magnitude. |
| NC | No connection | Pin 5 is internally unconnected; must remain floating per datasheet. |
| EP | Common drain thermal pad | Shared drain node for both MOSFETs; requires large copper pour for thermal dissipation and low-inductance current path. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual N-CH MOSFETs | Ultra-low RSS(ON) ≤16.5 mΩ eliminates need for discrete FETs and reduces BOM count by two components. |
| Programmable overcharge release | Auto-release mode enables automatic resumption of charging after voltage drops below VCL (e.g., 4.15 V), avoiding manual reset. |
| Built-in fixed delay timers | Eliminates external RC networks for tCU, tDL, tDOC, reducing component count and board space by ≥3 passive parts. |
| 0V battery charge support | Enables safe recharge of cells depleted to 0 V due to self-discharge, extending usable battery life in infrequently used devices. |
| Thermal pad (EP) design | Common-drain EP pad simplifies PCB layout and improves thermal resistance by >40% versus separate drain pads. |
Applications
| Power Tool Battery Packs | Wireless Earbud Charging Cases |
|---|---|

Use Value: Extends shelf life by >6 months without maintenance charging, while supporting rapid reactivation when first used after storage. |
| Portable Medical Monitors | Smart Wearable Fitness Trackers |
|
Use Scenario: FDA-cleared handheld ECG monitor requiring guaranteed runtime, fail-safe shutdown, and traceable protection logs. IC Role / Device Role / Timing Role: Safety-critical protection element enforcing strict overdischarge cutoff (2.5 V ±35 mV) and overvoltage charger lockout (8.0 V ±2 V). Use Value: Ensures uninterrupted operation down to 2.5 V and prevents unsafe charging from non-compliant adapters, meeting IEC 62368-1 requirements. |
Use Scenario: Slim wrist-worn tracker with 120 mAh cell, subject to mechanical stress, temperature swings (-10°C to +60°C), and irregular usage patterns. IC Role / Device Role / Timing Role: Adaptive protector with wide-temp voltage thresholds (±80 mV drift) and auto-wake-up mode to resume function after overdischarge without external intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Li+ battery protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP9214LA-AN-HSBR-7 | Same pinout and specs, but includes Auto-Wake-Up mode enabled (vs. AP9214L's Power-Down default); no 0V charge option. | Preferred where overdischarge recovery must occur without charger presence (e.g., remote sensors). | Select if system cannot guarantee charger availability during recovery; verify 0V charge not required. |
| SE9011B-XX-XXX | Single-MOSFET architecture; no integrated charge MOSFET; higher RSS(ON) (25 mΩ); lacks overvoltage charger detection. | Requires external charge FET and separate OV protection circuit; suitable only for cost-sensitive, low-power applications. | Choose only when BOM cost outweighs integration benefits and charger voltage is strictly regulated. |
Compared with AP9214LA-AN-HSBR-7, this part adds factory-configured 0V battery charge capability but retains identical timing and voltage accuracy; versus SE9011B, it delivers full dual-FET integration, faster short-circuit response, and charger-side overvoltage protection-critical for unregulated adapter environments.

FAQ
What is the function of the NC pin on AP9214L-AN-HSBR-7?
Pin 5 is designated NC (No Connection) in the HSBR pin-out option and must remain electrically floating. It is not bonded internally and has no functional role. Connecting it to any net-including ground or VSS-violates the datasheet specification and may cause undefined behavior or latch-up.
Does AP9214L-AN-HSBR-7 support overvoltage protection on the charger input side?
Yes. The device monitors the voltage between VDD and VM pins and triggers overvoltage charger protection at 8.0 V ±2 V (typical), turning off the charge MOSFET immediately without delay. Release occurs at 7.3 V ±2 V, providing robust safeguard against faulty or unregulated wall adapters.
How does the 0V battery charge feature operate in practice?
When battery voltage reaches 0 V, the AP9214L-AN-HSBR-7 permits charging if the applied charger voltage exceeds 1.2 V (start threshold). Charging continues until cell voltage rises above 0.45 V (inhibit threshold), enabling safe reactivation of deeply self-discharged cells without external intervention.
Can AP9214L-AN-HSBR-7 be used in automotive cabin modules?
No. While Diodes offers AEC-Q100-qualified variants in the AP9214 family (e.g., AP9214LQ), the AP9214L-AN-HSBR-7 is rated for industrial temperature range (−40°C to +85°C) and lacks PPAP documentation, IATF 16949 traceability, or automotive-grade qualification-making it unsuitable for automotive safety-critical systems.
