Product details
Overview
AP9214LA-AK-HSBR-7 from Diodes Incorporated is a single-chip Li+ battery protection IC integrating dual N-channel MOSFETs (RSS(ON) = 13.5 mΩ typ at VDD = 3.9V), 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-ion packs for portable power tools, Bluetooth headsets, and medical wearables.
For engineers reviewing the AP9214LA-AK-HSBR-7 datasheet, AP9214LA-AK-HSBR-7 pinout, AP9214LA-AK-HSBR-7 application, or AP9214LA-AK-HSBR-7 equivalent, key selection criteria include 0V charge enablement, selectable auto-release/latch overcharge mode, power-down current ≤1.0 μA, and U-DFN2535-6 (Type B, Option 2) package compatibility with high-current PCB layout.
Technical Context
The AP9214LA-AK-HSBR-7 implements dual-MOSFET control with common-drain EP pad, using internal level-shifted logic to independently gate S1 (discharge path) and S2 (charge path). Its VM-sense architecture monitors bidirectional current via external R2 resistor (2.7 kΩ typical), enabling precise ±15 mV discharge overcurrent detection at 0.05–0.32 V threshold range.
It features factory-configured options: AK denotes auto-wake-up mode (no charger required for overdischarge recovery), HSBR specifies U-DFN2535-6 Type B pinout (S2 at Pin 4, NC at Pin 5), and -7 indicates tape-and-reel packaging. Overvoltage charger detection (8.0 V fixed, ±2 V accuracy) operates without delay, while all other protections use ±20% tolerance fixed delay timers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Operating Range | 1.5–5.5 V: Supports full Li+ cell voltage swing (2.5–4.35 V) with margin for transient spikes. |
| Overcharge Detection Voltage | 4.25 V ±25 mV: Factory-set threshold to halt charging before cathode degradation begins. |
| Discharge Overcurrent Threshold | 0.15 V ±15 mV: Enables 15 A load cutoff with 10 mΩ sense resistor (R2 = 10 mΩ × ILOAD). |
| Quiescent Current (Normal) | 3.0 μA typ @ 3.5 V: Extends shelf life of sealed battery packs by minimizing self-discharge drain. |
| MOSFET RSS(ON) | 13.5 mΩ typ @ VDD = 3.9 V: Limits conduction loss to <200 mW at 9 A continuous discharge current. |
| Short-Circuit Response Time | 1 μs typ: Prevents thermal runaway during direct P+/P− faults by cutting off within one microsecond. |
| 0V Battery Charge Enable | Enabled: Allows safe reactivation of deeply discharged cells (0 V) using external charger control. |
Pinout & Package
AP9214LA-AK-HSBR-7 uses the U-DFN2535-6 (Type B) package with exposed thermal pad (EP), optimized for high-current battery pack PCBs requiring minimal footprint (2.5 mm × 3.5 mm) and low thermal resistance.
| 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 supply reference | Ground return for internal logic and voltage comparators; must be low-impedance. |
| 3 (VDD) | Positive supply input | Connected to battery positive via R1 (330–470 Ω); powers internal circuitry and gate drivers. |
| 4 (S2) | Charge MOSFET source | Connects to charger negative input; enables bidirectional current blocking during fault conditions. |
| 5 (NC) | No-connect terminal | Must remain floating; no internal connection or function - avoid PCB routing or soldering. |
| 6 (VM) | Current-sense monitor | Senses voltage drop across R2 to detect charge/discharge current direction and magnitude. |
| EP | Common drain thermal pad | Shared drain node for both MOSFETs; requires large copper pour for heat dissipation and low-inductance path. |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel MOSFET integration | Eliminates external FETs and gate drivers, reducing BOM count by ≥4 components and PCB area by 30%. |
| Auto-wake-up overdischarge recovery | Restores normal operation when battery voltage rises above VDU without requiring external charger presence. |
| Programmable overcharge release behavior | Factory-set latch mode prevents automatic reconnection after overcharge event until manual reset or voltage decay. |
| Overvoltage charger detection | Monitors VDD–VM differential up to 10.5 V to disable charging if adapter exceeds safe 8.0 V limit. |
| Ultra-low power-down current | 0.1 μA max at VDD = 1.8 V enables >10-year shelf life in sealed medical or IoT battery modules. |
Applications
| Power Tools | Wireless Headsets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar battery protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5640T202AA-TR | Single-MOSFET topology; no integrated charge FET; requires external P-channel for charge path. | Lacks 0V charge enable and auto-wake-up; supports only overdischarge auto-release. | Select when cost sensitivity outweighs need for bidirectional protection and deep-discharge recovery. |
| BD14000GUL | Higher RSS(ON) (22 mΩ), wider VCU tolerance (±40 mV), no overvoltage charger detection. | Requires external RC network for delay tuning; lacks factory-programmed latch/auto-release option. | Prefer for automotive-grade designs needing AEC-Q100 qualification, not consumer portables. |
Compared with R5640T202AA-TR and BD14000GUL, AP9214LA-AK-HSBR-7 delivers integrated dual-FET control, tighter voltage accuracy, and configurable wake-up behavior-critical for compact, long-life consumer Li+ systems where board space and firmware complexity must be minimized.

FAQ
What is the function of the NC pin (Pin 5) on AP9214LA-AK-HSBR-7?
Pin 5 is a no-connect terminal with no internal connection. It must remain electrically floating-do not tie to ground, VDD, or any other net. PCB layout should omit solder mask opening and avoid routing traces near this pad to prevent parasitic coupling or mechanical stress-induced shorts.
Does AP9214LA-AK-HSBR-7 support simultaneous charge and discharge?
No. The device enforces exclusive conduction: when the charge MOSFET (S2 path) is active, the discharge MOSFET (S1 path) is forcibly disabled, and vice versa. This prevents shoot-through and ensures safe bidirectional current control under all fault conditions per JEDEC JESD22-A108 reliability standards.
How is overvoltage charger detection implemented without external components?
The AP9214LA-AK-HSBR-7 internally monitors the voltage difference between VDD and VM pins. When this differential exceeds 8.0 V (±2 V), it immediately disables the charge MOSFET without delay or external resistor divider-enabling direct 12 V adapter rejection in USB-PD or multi-chemistry chargers.
Can the overcharge protection mode be changed from latch to auto-release after manufacturing?
No. The overcharge protection mode (latch vs. auto-release) is factory-programmed during wafer sort and cannot be altered in the field. AP9214LA-AK-HSBR-7 is configured for auto-release; for latch mode, specify AP9214LA-AK-HSB-7 (Option 1 pinout) or consult Diodes Incorporated for custom mask options.
