Product details
Overview
AP9214L-AG-HSB-7 from Diodes Incorporated is a single-chip Li+ battery protection IC integrating dual N-channel MOSFETs (RSS(ON) ≤ 16 mΩ @ VDD = 4.0V), overcharge/overdischarge voltage detection (±25 mV accuracy), discharge overcurrent sensing (±15 mV), and short-circuit protection with 1.2 µs detection delay. It operates in 1-cell Li+ battery packs for portable power tools and medical devices requiring ultra-low quiescent current (3.0 µA typ).
For engineers reviewing the AP9214L-AG-HSB-7 datasheet, AP9214L-AG-HSB-7 pinout, AP9214L-AG-HSB-7 application, or AP9214L-AG-HSB-7 equivalent, key selection criteria include selectable power-down mode, 0V battery charge enable, auto-release vs. latch overcharge protection, and U-DFN2535-6 (Type B, Option 1) package compatibility with high-current PCB layout.
Technical Context
The AP9214L-AG-HSB-7 implements independent analog voltage comparators for VDD–VSS (cell voltage) and VM–VSS (current-sense differential), with fixed internal delay timers (tCU = 1.0 s typ, tSHORT = 1.2 µs typ) and logic-controlled gate drivers for dual N-MOSFETs sharing a common drain (EP pad). Its architecture supports simultaneous charge/discharge path control without external timing components.
It features factory-configurable options: power-down mode (enabled), 0V battery charge function (enabled), and overcharge protection release behavior (auto-release). The VM pin interfaces via external R2 (2.7 kΩ typical) to sense bidirectional current flow, while VDD is supplied through R1 (330–470 Ω) for supply stabilization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Operating Range | 1.5 V to 5.5 V - supports full Li+ cell voltage range (2.5 V–4.4 V) with margin for transient spikes |
| Overcharge Detection Voltage | 4.250 V ±25 mV - precise cutoff at standard Li+ upper limit prevents cell degradation |
| Discharge Overcurrent Threshold | 0.150 V ±15 mV - enables accurate current limiting using low-value sense resistor (e.g., 5 mΩ yields 30 A trip) |
| Quiescent Current (Normal) | 3.0 µA typ @ +25°C - extends battery shelf life in standby without compromising protection responsiveness |
| Short-Circuit Detection Delay | 1.2 µs typ - shuts down discharge path before fault energy damages MOSFET or load |
| MOSFET RSS(ON) | 13 mΩ max @ VDD = 4.0 V - minimizes conduction loss and thermal rise during 9 A continuous discharge |
| Operating Temperature | −40°C to +85°C - qualified for industrial and portable equipment environments |
Pinout & Package
AP9214L-AG-HSB-7 uses the U-DFN2535-6 (Type B, Option 1) package: 2.5 mm × 3.5 mm, 0.5 mm pitch, exposed thermal pad (EP) for enhanced heat dissipation. Pin 5 is NC (no connect); EP must be soldered to large copper area for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1 | Source of discharge MOSFET | Connects directly to battery negative terminal; carries full load current during discharge |
| VSS | Negative power supply reference | Ground return for all internal comparators and logic; must be low-impedance path |
| VDD | Positive supply input | Connected to battery positive via R1 (330–470 Ω); powers internal circuitry and gate drivers |
| VM | Current-sense input | Monitors voltage drop across R2 to detect charge/discharge current direction and magnitude |
| NC | No connection | Pin 5 must remain floating; no trace or solder mask should contact this pad |
| S2 | Source of charge MOSFET | Connects to charger negative input; enables bidirectional current control with S1 |
| EP | Common drain thermal pad | Shared drain node for both MOSFETs; requires ≥ 25 mm² copper pour for 1000 mW power dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual N-MOSFETs | Eliminates discrete FETs and gate drivers, reducing BOM count and PCB area by >40% vs. discrete solutions |
| Factory-set 0V battery charge | Enables safe recharge of deeply discharged cells (0 V) without external wake-up circuitry |
| Selectably latched overcharge protection | Prevents automatic reconnection after overvoltage event unless manually reset via charger disconnect/reconnect |
| Built-in VM pull-up/pull-down resistors | RVMD (300 kΩ typ) and RVMS (30 kΩ typ) eliminate external biasing components for status monitoring |
| Ultra-low power-down current | 0.1 µA max enables multi-year storage life for battery-powered IoT sensors and medical patches |
Applications
| Power Tools | Medical Wearables |
|---|---|
|
Use Scenario: Cordless drill battery pack with 20 A peak discharge and frequent deep cycling. IC Role / Device Role / Timing Role: Primary protection controller managing charge/discharge paths, detecting overcurrent within 1.2 µs during motor stall events. Use Value: Prevents MOSFET thermal runaway during sustained high-current loads while maintaining <3 µA self-discharge during tool idle periods. |
Use Scenario: Rechargeable ECG patch with 12-month shelf life and strict leakage current limits. IC Role / Device Role / Timing Role: Battery safety supervisor enabling 0V recovery and entering 0.1 µA power-down mode after overdischarge. Use Value: Extends usable battery life by 30% versus discrete protection ICs due to integrated low-IQ design and no external bias networks. |
| Portable Diagnostic Scanners | Smart Lock Batteries |
|
Use Scenario: Handheld ultrasound scanner requiring rapid charge acceptance and robust short-circuit immunity. IC Role / Device Role / Timing Role: Dual-path protector enforcing ±15 mV overcurrent threshold and 8.0 V overvoltage charger cutoff. Use Value: Guarantees safe operation with fast-charging adapters up to 5 V/3 A while rejecting faulty >8 V chargers before damage occurs. |
Use Scenario: Bluetooth-enabled smart lock with infrequent but critical high-current actuation (e.g., solenoid strike). IC Role / Device Role / Timing Role: Fail-safe battery guard triggering 1.2 µs short-circuit shutdown during solenoid coil faults. Use Value: Avoids permanent lock failure by isolating fault current before PCB trace fusing or MOSFET destruction. |
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 | Higher quiescent current (5 µA typ), no integrated MOSFETs, requires external dual-N FETs | Lacks 0V charge support and power-down mode; suited for cost-sensitive designs where board space is not constrained | Choose when external FET selection flexibility outweighs integration benefits and leakage budget allows +2 µA increase |
| Ricoh RP505K001B-TR-F | Fixed 4.25 V overcharge threshold (no programmability), 20 mΩ RSS(ON), no overvoltage charger detection | Omits 8.0 V charger overvoltage protection and has lower accuracy (±30 mV) on overdischarge detection | Select only if charger overvoltage risk is mitigated externally and ±5 mV tighter VDL tolerance is unnecessary |
Compared with S-8261AAL-M6T1U and RP505K001B-TR-F, the AP9214L-AG-HSB-7 delivers superior integration (dual MOSFETs + protection logic), tighter voltage accuracy (±25 mV), and unique features including 0V charge enable and overvoltage charger cutoff-critical for unattended portable systems.

FAQ
What is the function of the NC pin (Pin 5) on AP9214L-AG-HSB-7?
Pin 5 is a no-connect terminal in U-DFN2535-6 (Type B, Option 1) configuration and must remain electrically floating. It is not internally bonded and has no circuit function; PCB layout must avoid routing traces or applying solder mask over this pad to prevent unintended shorts or parasitic coupling.
How does the 0V battery charge feature operate in AP9214L-AG-HSB-7?
The 0V battery charge function is factory-enabled in the -AG variant and allows the IC to exit power-down mode when a charger applies voltage-even if the cell voltage is 0 V. It activates internal wake-up circuitry that pulls up VM via RVMD, enabling charging current to flow once VDD rises above 1.2 V, per datasheet V0CHA specification.
Can AP9214L-AG-HSB-7 support both charge and discharge current limiting independently?
Yes. The IC uses separate voltage thresholds: VCOC (−0.05 V typ) for charge overcurrent and VDOC (+0.15 V typ) for discharge overcurrent. Each triggers independent MOSFET shutdown-S2 for charge faults, S1 for discharge faults-enabling asymmetric current protection tailored to charger and load characteristics.
What thermal design guidance applies to the EP pad of AP9214L-AG-HSB-7?
The EP pad is the common drain node for both MOSFETs and must be soldered to ≥ 25 mm² of 2-ounce copper on the PCB's inner or bottom layer. Thermal vias (≥ 6× 0.3 mm diameter) should connect EP to internal ground planes to maintain junction temperature below +150°C at 9 A continuous current, per absolute maximum ratings.
