Product details
Overview
AP9214LA-AH-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) in a U-DFN2535-6 (Type B, Option 2) package. It provides overcharge (3.85V ±25mV), overdischarge (2.50V ±35mV), discharge/charge overcurrent (±15mV accuracy), and short-circuit protection for 1-cell Li-ion packs used in portable power tools and medical handheld devices.
For engineers reviewing the AP9214LA-AH-HSBR-7 datasheet, AP9214LA-AH-HSBR-7 pinout, AP9214LA-AH-HSBR-7 application, or AP9214LA-AH-HSBR-7 equivalent, this device supports selectable auto-wake-up mode, 0V battery charge enable, and fixed delay timing-critical for BMS reliability in space-constrained consumer and industrial battery packs.
Technical Context
The AP9214LA-AH-HSBR-7 implements dual independent protection paths: one for charging (controlled via S2/VM/VDD) and one for discharging (controlled via S1/VM/VSS), with internal level-shifting logic enabling MOSFET gate drive from a single 1.5–5.5V supply. Its VM pin senses bidirectional current through an external sense resistor (R2 = 2.7kΩ typical) to detect both charge and discharge overcurrent events.
It features factory-programmed voltage thresholds: overcharge detection at 3.85V (±25mV), overdischarge at 2.50V (±35mV), discharge overcurrent at 0.15V (±15mV), and short-circuit at 0.60V (±100mV). Delay times-including tSHORT = 1.2μs (±20%)-are internally fixed to eliminate external RC components and reduce BOM count.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 1.5V to 5.5V: Enables direct connection to Li+ cell voltage without external regulator. |
| RSS(ON) (Discharge) | 13.5 mΩ typ @ VDD = 3.9V: Limits I²R loss during 9A continuous discharge (TA = +25°C). |
| IQ (Normal Mode) | 3.0 µA typ @ +25°C: Extends shelf life of dormant battery packs. |
| Overcharge Accuracy | ±25 mV @ +25°C: Ensures safe cell voltage clamping within JEITA-recommended limits. |
| tSHORT | 1.2 µs typ (±20%): Enables sub-microsecond short-circuit shutdown before PCB trace damage. |
| 0V Charge Enable | Factory-set active: Allows recovery of deeply discharged cells without manual pre-charge circuitry. |
| Power-Down Mode | Disabled (Auto-Wake-Up): Permits automatic recovery from overdischarge when load is removed and voltage rises. |
Pinout & Package
Package: U-DFN2535-6 (Type B), 2.5mm × 3.5mm × 0.55mm, exposed thermal pad (EP), RoHS-compliant, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S1) | Discharge MOSFET source | Connects directly to battery negative terminal; carries full load current path. |
| 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 (330–470Ω); powers internal circuitry and gate drivers. |
| 4 (VM) | Current sense & charger status monitor | Senses voltage drop across R2 to detect charge/discharge direction and magnitude; enables overvoltage charger detection. |
| 5 (S2) | Charge MOSFET source | Connects to charger negative input; isolates charger during overvoltage or overcurrent fault. |
| 6 (NC) | No connect | 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 dissipation and low-inductance switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual integrated N-MOSFETs | Eliminates discrete FET selection, layout complexity, and gate-drive matching issues in compact 1-cell BMS designs. |
| Fixed internal delay timers | Removes need for external RC networks-reducing component count, board area, and calibration risk. |
| Selectable 0V battery charge | Enables automatic recharge of cells depleted to 0V due to self-discharge, improving field reliability without user intervention. |
| Auto-Wake-Up mode | Allows autonomous recovery from overdischarge when load is disconnected and cell voltage recovers above VDU, avoiding manual reset. |
| Overvoltage charger detection | Monitors VDD–VVM up to 8.0V (±2V) to disable charging if faulty or mismatched charger is attached. |
Applications
| Power Tools | Medical Handheld Devices |
|---|---|

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-8261AAL-M6T1U | Separate charge/discharge FET control; no integrated MOSFETs; higher quiescent current (5.5µA). | Requires external dual-N MOSFETs and gate resistors; increases layout area and BOM count. | Preferred where discrete FET selection is needed for thermal or voltage rating flexibility. |
| Ricoh RP505K001B-TR-F | Single integrated MOSFET (discharge only); no charge-path FET; lacks 0V charge function. | Cannot block charger during overvoltage events; requires external P-FET for charge control. | Only suitable for cost-sensitive applications where charger-side protection is handled externally. |
Compared with S-8261AAL-M6T1U and RP505K001B-TR-F, the AP9214LA-AH-HSBR-7 delivers lower system-level BOM cost, smaller footprint, and superior functional integration-including simultaneous charge/discharge MOSFET control, 0V charge enable, and overvoltage charger detection-without external components.

FAQ
What is the difference between AP9214LA-AH-HSBR-7 and AP9214L-AH-HSB-7?
The AP9214LA-AH-HSBR-7 uses Pin-Out Option 2 (S2 on pin 5, NC on pin 4), while AP9214L-AH-HSB-7 uses Option 1 (S2 on pin 4, NC on pin 5). Both share identical electrical specifications and protection functions, but PCB layout must match the assigned pin mapping to ensure correct MOSFET source routing and VM sensing.
Does AP9214LA-AH-HSBR-7 support overvoltage protection on the charger side?
Yes-it monitors the voltage between VDD and VM pins and triggers charging MOSFET shutdown if it exceeds 8.0V (±2V), releasing at 7.3V (±2V). This protects against damaged or mismatched chargers without requiring external components or delay configuration.
Can AP9214LA-AH-HSBR-7 recover from overdischarge without a charger connected?
Yes-because it is the "A" variant (Auto-Wake-Up mode), it exits overdischarge state automatically when battery voltage rises above the overdischarge release voltage (VDU = 2.70V) and remains there for tDLR (typically 1.2s), even with no charger present.
What is the maximum continuous discharge current supported by AP9214LA-AH-HSBR-7?
At TA = +25°C, the device supports 9.0A continuous drain current with VGS = 4.5V. At +70°C, derating applies to 7.1A. Thermal performance depends on PCB copper area under the EP pad; ≥100mm² recommended for sustained 7A operation.
