Product details
Overview
AP22814BSN-7 from Diodes Incorporated is a single-channel, active-low enable, high-side load switch optimized for USB and hot-swap applications. It delivers 3.0 A continuous output current with 50 mΩ RDS(ON), integrated reverse-current blocking, over-current/over-temperature/short-circuit protection with auto-recovery, and 6 ms deglitched fault reporting via open-drain FLG pin. Used in SSD power rails and ultrabook sequencing.
For engineers reviewing the AP22814BSN-7 datasheet, AP22814BSN-7 pinout, AP22814BSN-7 application, or AP22814BSN-7 equivalent, key selection criteria include input voltage range (2.7–5.5 V), thermal shutdown threshold (+140 °C), soft-start rise time (2.1 ms typ), reverse-voltage trip point (50 mV), and U-DFN2020-6 package thermal resistance (RθJA = 100 °C/W).
Technical Context
The AP22814BSN-7 integrates an N-channel MOSFET power switch with current-sense FET-based overload detection, eliminating external sense resistors. Its UVLO activates at 2.0 V (with 180 mV hysteresis) and disables the switch below that threshold to prevent unstable operation during brown-out conditions.
Thermal protection uses die-temperature sensing with +140 °C shutdown and +35 °C hysteresis, enabling safe cycling under sustained short-circuit faults. The 6 ms deglitch on FLG prevents false triggering from capacitive inrush transients, while the internal discharge path (90–130 Ω) actively discharges the output capacitor when disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports full USB 2.0/3.0 bus voltage tolerance and battery-backed 3.3 V systems. |
| RDS(ON) | 50 mΩ typ - enables <150 mW conduction loss at 3.0 A, reducing thermal stress in compact U-DFN2020-6 package. |
| Output Current Limit | 3.45 A typ - sustains 3.0 A continuous load with margin for transient peaks without latch-off. |
| FLG Blanking Time | 6 ms typ - suppresses false fault signals during hot-plug inrush into 120 μF+ loads without external RC filtering. |
| Reverse-Voltage Trip | 50 mV - blocks reverse current when VOUT exceeds VIN by ≥50 mV, protecting upstream sources in back-fed scenarios. |
| Discharge Resistance | 90–130 Ω - fully discharges 1 μF output capacitance in ≤0.4 ms, preventing floating rail issues during power-down. |
| Thermal Shutdown | +140 °C with +35 °C hysteresis - allows safe thermal cycling under persistent overload without permanent disable. |
Pinout & Package
AP22814BSN-7 is housed in a RoHS-compliant, thermally enhanced U-DFN2020-6 package with exposed thermal pad (recommended to connect to PCB ground plane). Dimensions: 2.0 mm × 2.0 mm × 0.65 mm.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Power input pin; requires 1 μF low-ESR ceramic capacitor to GND for stability and noise suppression. |
| 2 | GND | Ground reference for control circuitry and power return; must be connected to thermal pad for optimal heat dissipation. |
| 3 | FLG | Open-drain fault flag; pulls low after 6 ms deglitch upon over-current or over-temperature event. |
| 4 | EN | Active-low enable input; logic low (<0.65 V) disables switch and activates discharge path. |
| 5 | OUT | Switched output; connects to load and requires 0.1 μF + ≥10 μF bulk capacitance to GND for USB compliance. |
| 6 | NC | No internal connection; electrically isolated and may be left unconnected or tied to GND for mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft-start | 2.1 ms typical rise time - limits inrush current into heavy capacitive loads (e.g., 120 μF SSD rails) to avoid supply droop. |
| Integrated output discharge | 90–130 Ω discharge path - eliminates need for external bleed resistor, ensuring rapid, controlled VOUT decay on disable. |
| Reverse-current blocking | 50 mV trip threshold - prevents backfeed from downstream circuits (e.g., powered USB peripherals) into main supply rail. |
| Auto-recovery protection | Over-current, short-circuit, and over-temperature faults self-clear once condition resolves - no manual reset required. |
| UVLO with hysteresis | 2.0 V turn-on / 1.82 V turn-off - ensures clean power-up sequencing and avoids oscillation near brown-out thresholds. |
Applications
| USB 3.0 Port Power Switching | SSD Power Rail Sequencing |
|---|---|
|
Use Scenario: Hot-plug insertion of USB 3.0 peripherals into ultrabook or docking station ports. IC Role / Device Role: High-side load switch controlling 5 V bus power delivery with inrush limiting and short-circuit robustness. Use Value: Prevents host port damage from cable shorts or capacitive inrush; FLG signal alerts system controller of fault events. |
Use Scenario: Enabling/disabling 3.3 V or 5 V power to NAND flash modules in M.2 or SATA SSDs during sleep/wake transitions. IC Role / Device Role: Controlled power gate with reverse-current blocking to isolate SSD from host during suspend. Use Value: Eliminates leakage paths that drain host battery; discharge function clears residual charge before re-enabling. |
| Ultrabook Power-Up Sequencing | Set-Top Box Peripheral Power Management |
|
Use Scenario: Staged activation of display backlight, audio codec, and I/O controllers during boot to limit peak input current. IC Role / Device Role: Individually controllable high-side switch with precise timing via GPIO-driven EN pin. Use Value: Enables deterministic power ramp rates per subsystem; soft-start prevents shared rail collapse across multiple rails. |
Use Scenario: Independent power control for HDMI receiver, tuner, and USB host ports in consumer STBs to meet standby power regulations. IC Role / Device Role: Low-quiescent-current (80 µA typ) load switch with thermal resilience in enclosed chassis environments. Use Value: Maintains reliable operation at +85 °C ambient; auto-recovery avoids field failures from transient overloads. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL7407LDR | 7-channel, 500 mA per channel, open-drain sink driver; no integrated discharge or reverse-blocking. | Designed for LED/relay driving, not hot-swap power gating; lacks UVLO, thermal shutdown, and current limiting. | Select only if multi-channel sinking (not sourcing) and no protection features are required. |
| TPS22915BYFPR | Single-channel, 2 A, 44 mΩ RDS(ON), active-high enable, 1.2 ms rise time; no reverse-voltage protection. | Optimized for space-constrained mobile apps; missing reverse-current blocking and 50 mV trip comparator. | Prefer when lower on-resistance and faster turn-on are critical, and reverse feed is not a system concern. |
Compared with TPL7407LDR and TPS22915BYFPR, AP22814BSN-7 uniquely combines 3.0 A rating, reverse-voltage protection, auto-recovery thermal management, and U-DFN2020-6 footprint-making it suitable for USB-compliant, high-reliability hot-swap power domains where backfeed prevention and fault resilience are mandatory.

FAQ
What is the maximum continuous output current supported by AP22814BSN-7?
The AP22814BSN-7 supports 3.0 A continuous output current at 25 °C ambient, with current-limit threshold specified at 3.45 A (typ) under 5 V input and 4.5 V output conditions. Derating applies above 25 °C per RθJA = 100 °C/W and thermal shutdown at +140 °C junction temperature.
Does AP22814BSN-7 require external components for fault reporting or discharge?
No external components are required for fault reporting or discharge. The 6 ms deglitch on the FLG pin is fully internal, and the discharge path (90–130 Ω) activates automatically when EN is de-asserted-eliminating need for external resistors or RC networks in standard USB and SSD implementations.
How does reverse-voltage protection operate in AP22814BSN-7?
When VOUT exceeds VIN by ≥50 mV for ≥6 ms, the internal MOSFET turns off to block reverse current. Recovery occurs automatically when the reverse condition ends, with no latch or manual reset needed. This protects upstream supplies from backfeed in multi-rail or hot-plug systems.
Can AP22814BSN-7 be used in place of AP22804BSN-7?
Yes, but only where 3.0 A output capability is required. AP22814BSN-7 has higher current limit (3.45 A typ vs. 3.0 A typ for AP22804BSN-7) and identical pinout, protection features, and timing characteristics. Substitution is electrically safe but should be verified against actual load current and thermal margins in the target design.
