Product details
Overview
AP9214L-AA-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 μs response. It operates in 1-cell Li+ battery packs for portable power tools, Bluetooth headsets, and medical wearables.
For engineers reviewing the AP9214L-AA-HSBR-7 datasheet, AP9214L-AA-HSBR-7 pinout, AP9214L-AA-HSBR-7 application, or AP9214L-AA-HSBR-7 equivalent, key selection criteria include selectable power-down mode, 0V battery charge enable, overcharge auto-release/latch configuration, and U-DFN2535-6 (Type B, Option 2) package compatibility with thermal pad grounding.
Technical Context
The AP9214L-AA-HSBR-7 implements dual independent protection paths: one for charging (controlled via S2–VM–VDD loop with VCOC = –0.05 V to –0.2 V detection) and one for discharging (via S1–VM–VSS loop with VDOC = 0.05 V to 0.32 V). Its internal logic uses fixed delay timers (tCU/tDL = ±20% accuracy) and level-shifted gate drivers to control common-drain MOSFETs without external components.
It features factory-configurable options embedded in the part number: "AA" denotes VCU = 4.25 V / VCL = 4.15 V / VDL = 2.50 V / VDU = 2.70 V / VDOC = 0.100 V / VSHORT = 0.55 V / VCOC = –0.100 V; "HSBR" specifies Pin-Out Option 2 (VM on Pin 4, S2 on Pin 5, NC on Pin 5); and "7" indicates tape-and-reel packaging (3000 pcs/reel).
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 (VCU) | 4.25 V ±25 mV - precise termination at standard Li+ full-charge threshold |
| Discharge Overcurrent Threshold (VDOC) | 0.100 V ±15 mV - enables 10 A continuous discharge with 10 mΩ effective sense resistance |
| Quiescent Current (Normal Mode) | 3.0 µA typ @ +25°C - extends battery shelf life in standby without compromising responsiveness |
| MOSFET RSS(ON) | 13.5 mΩ max @ VDD = 3.9 V - minimizes conduction loss and self-heating during 7.1 A continuous discharge |
| Short-Circuit Response Time | 1 µs typ - prevents catastrophic failure during sub-millisecond fault events |
| 0V Battery Charge Enable | Factory-set active - allows safe recharge of fully depleted cells without manual intervention |
Pinout & Package
AP9214L-AA-HSBR-7 is housed in a thermally enhanced U-DFN2535-6 (Type B) package with exposed drain thermal pad (EP). Pin-Out Option 2 places VM on Pin 4 and S2 on Pin 5, enabling direct routing to charger-side current-sense resistors while isolating NC (Pin 5 in Option 1) as floating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1 (Pin 1) | Discharge MOSFET source | Connects directly to battery negative terminal; forms low-impedance discharge path with EP |
| VSS (Pin 2) | Negative supply reference | Ground return for all internal comparators and logic; must be low-inductance connection |
| VDD (Pin 3) | Positive supply input | Connected to battery positive via R1 (330–470 Ω); powers internal circuitry and gate drivers |
| VM (Pin 4) | Charge/discharge current sense input | Monitors voltage drop across R2 (2.7 kΩ typical) between P− and S2; determines charge/discharge state |
| S2 (Pin 5) | Charge MOSFET source | Connects to charger negative input; enables independent charge-path control and overvoltage charger detection |
| NC (Pin 5 in Option 1, not used here) | No connection | Left floating per design; no PCB trace required for HSBR variant |
| EP (Thermal Pad) | Common drain node | Shared drain for both MOSFETs; requires large copper pour for thermal dissipation and low-impedance GND tie |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual N-MOSFETs | Eliminates discrete FET layout complexity and reduces BOM count by two high-side switches |
| Programmable overcharge release mode | Auto-release or latch behavior configurable at factory - ensures compliance with pack safety standards |
| Built-in fixed delay timers | Removes need for external RC networks; tCU/tDL accuracy ±20% avoids false triggers during transient spikes |
| Overvoltage charger detection (8.0 V) | Protects against faulty chargers exceeding 2× nominal cell voltage without external Zener or divider |
| Power-down mode (enabled) | Reduces quiescent current to ≤1.0 µA over full temperature range - critical for multi-year IoT device battery life |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Li+ battery protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5460K001C-TR | Single-MOSFET architecture; no integrated charge MOSFET; VCU = 4.25 V but no overvoltage charger detection | Lacks dual-path protection; requires external P-channel FET for charge control and separate OVP circuit | Select only if cost sensitivity outweighs board space and safety certification burden |
| BD8630GUL | Higher RSS(ON) (25 mΩ); no 0V charge function; fixed auto-release only; tSHORT = 5 µs (vs. 1 µs) | Slower short-circuit response increases risk of PCB trace melting under 15 A faults | Acceptable for low-power sensors but unsuitable for power tools or medical devices with IEC 62368-1 requirements |
Compared with R5460K001C-TR and BD8630GUL, AP9214L-AA-HSBR-7 delivers faster fault response, integrated dual-FET topology, and factory-configured safety features-reducing design validation effort and enabling UL/IEC 62133-compliant pack certification without external components.

FAQ
What is the function of the EP (exposed pad) on AP9214L-AA-HSBR-7?
The EP serves as the common drain terminal for both integrated N-channel MOSFETs. It must be soldered to a large PCB copper area tied to system ground to dissipate up to 1000 mW of power and maintain junction temperature below +150°C during 9 A continuous operation. Thermal vias beneath the pad improve heat transfer to inner layers.
How does the VM pin enable both charge and discharge current monitoring?
VM senses voltage between the battery's P− node and S2 (charge path) or S1 (discharge path) through external resistor R2. During charging, VM voltage drops below VSS when VCOC is exceeded; during discharging, VM rises above VSS when VDOC is exceeded. Internal RVMS/RVMD resistors pull VM to VSS or VDD respectively to distinguish direction without polarity-switching circuitry.
Can AP9214L-AA-HSBR-7 support battery packs with higher than 1-cell configuration?
No. The AP9214L-AA-HSBR-7 is strictly rated for 1-cell Li+ systems with VDD–VSS operating range of 1.5 V to 5.5 V. Its overcharge detection (max 4.5 V) and absolute maximum VDS (24 V) are incompatible with 2-cell (8.4 V) or higher configurations. For multi-cell packs, Diodes' AP9221 series or standalone protection ICs with cascaded architecture are required.
What distinguishes Pin-Out Option 2 (HSBR) from Option 1 (HSB)?
HSBR swaps VM and S2 positions: VM moves to Pin 4 and S2 to Pin 5, while Pin 5 in HSB becomes NC. This routing simplifies PCB layout for charger-integrated designs by placing VM adjacent to VDD and S2 near the thermal pad, reducing trace inductance in high-current charge paths and avoiding signal crosstalk between VM and S1 discharge lines.
