Product details
Overview
AP22804ASN-7 from Diodes Incorporated is a single-channel, current-limited, high-side load switch optimized for USB and hot-swap applications. It features 50 mΩ RDS(ON), 2.7–5.5 V input range, 2.5 A continuous output current (AP22804), integrated output discharge, reverse-voltage protection (50 mV trip), and 6 ms deglitch on the open-drain FLG pin - enabling robust power sequencing in ultrabooks and SSDs.
For engineers reviewing the AP22804ASN-7 datasheet, AP22804ASN-7 pinout, AP22804ASN-7 application, or AP22804ASN-7 equivalent, key selection criteria include its U-DFN2020-6 thermal performance (RθJA = 100 °C/W), active-high enable logic (A suffix), controlled 2.1 ms typical rise time, and auto-recovering over-current/over-temperature protection without external components.
Technical Context
The AP22804ASN-7 integrates an N-channel MOSFET with precision current-sense FET architecture to deliver accurate 3.0 A overload limit (typ.) and 0.45 A short-circuit clamp, eliminating external sense resistors. Its UVLO (2.0 V threshold, 180 mV hysteresis) and reverse-voltage comparator (50 mV trip, 6 ms delay) operate independently of enable state.
Thermal shutdown activates at +140 °C with +35 °C hysteresis, causing cyclical recovery until fault removal. The FLG pin asserts low only after confirmed over-current or over-temperature events survive the 6 ms deglitch window - preventing false triggers from inrush or capacitive transients.
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 range with margin for ripple and drop. |
| RDS(ON) | 50 mΩ (typ.) at VIN = 5 V, IOUT = 1 A - limits conduction loss to ≤125 mW at 2.5 A, enabling compact thermal design in U-DFN2020-6. |
| Output Current Limit | 2.7–3.3 A (typ. 3.0 A) - sustains full-load operation under sustained overload without latch-off, supporting hot-plug insertion. |
| Rise Time (tR) | 1.0–3.5 ms (typ. 2.1 ms) - soft-start prevents inrush current spikes into large output capacitance (e.g., 120 μF in SSDs). |
| FLG Blanking Time | 2–13 ms (typ. 6 ms) - suppresses transient over-current pulses during capacitor charging, eliminating need for external RC filtering. |
| Reverse-Voltage Trip | 25–75 mV (typ. 50 mV) - blocks backfeed from powered downstream rails (e.g., USB OTG), protecting upstream source. |
| Discharge Resistance | 90–130 Ω (typ. 110 Ω) - actively discharges output to <0.5 V within 0.4 ms when disabled, ensuring safe hot-removal. |
Pinout & Package
AP22804ASN-7 uses the U-DFN2020-6 package (2.0 mm × 2.0 mm, 0.65 mm height) with exposed thermal pad recommended for external GND connection to improve power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Switched Output | Drives load; requires 0.1 μF ceramic + ≥10 μF bulk capacitor to GND for stability and short-circuit immunity. |
| 2 (GND) | Power Ground | Reference for internal circuitry and current sensing; must be low-impedance connection to system ground plane. |
| 3 (FLG) | Open-Drain Fault Flag | Active-low signal indicating over-current or over-temperature; pulled up externally (e.g., 10 kΩ to VIN). |
| 4 (EN) | Enable Input (Active High) | Logic-compatible control: ≥1.5 V enables switch; ≤0.65 V disables; must not float - tie to GND via 100 kΩ if unused. |
| 5 (IN) | Input Power Supply | Accepts 2.7–5.5 V; requires 1 μF X7R/X5R ceramic bypass capacitor placed adjacent to pin. |
| 6 (NC) | No Internal Connection | Unbonded pad; electrically isolated - may be left floating or connected to GND for mechanical stability only. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Soft-Start | 0.6 ms typical rise time ensures controlled turn-on into heavy capacitive loads (e.g., 120 μF SSD rails) without supply droop. |
| Auto-Recovering Protection | Over-current, short-circuit, and over-temperature faults self-clear once condition resolves - no manual reset required. |
| Reverse-Current Blocking | Blocks >400 mA reverse current when VOUT – VIN ≥ 100 mV, preventing backfeed damage in multi-rail systems. |
| Thermally Optimized Package | U-DFN2020-6 achieves RθJC = 20 °C/W - enables 2.5 A continuous operation at +85 °C ambient with minimal PCB copper. |
| UVLO with Hysteresis | Turns on only above 2.0 V and stays on until VIN drops to 1.82 V - prevents erratic switching during brown-out or hot-insertion. |
Applications
| Ultrabook Power Sequencing | SSD Hot-Swap Interface |
|---|---|
|
Use Scenario: Controlled power-up/down of discrete subsystems (e.g., USB-C port, display backlight) during sleep/wake transitions in thin-client notebooks. IC Role / Device Role / Timing Role: High-side load switch managing rail isolation and sequencing timing; enables precise 2.1 ms rise/fall control per USB compliance. Use Value: Eliminates need for discrete MOSFET + gate driver + protection IC, reducing BOM count by 4 components and PCB area by >30%. |
Use Scenario: Safe insertion/removal of M.2 NVMe SSDs in portable workstations where main 3.3 V rail remains live. IC Role / Device Role / Timing Role: Reverse-voltage blocking and inrush limiting element; discharges SSD's 100 μF output cap to <0.5 V within 0.4 ms upon removal. Use Value: Prevents backfeed into host controller and eliminates destructive voltage transients during hot-swap - certified per USB 3.2 Gen 2 requirements. |
| Set-Top Box USB Hub | Tablet PC Peripheral Port |
|
Use Scenario: Individual power control for downstream USB peripherals (HDD, camera) in consumer STBs to meet Energy Star standby leakage limits. IC Role / Device Role / Timing Role: Load switch enforcing <1 µA shutdown current (ISHDN) and 80 µA quiescent draw (IQ) in enabled state. Use Value: Reduces system standby power by 120 µA per port versus discrete solutions, extending compliance margin for <100 mW total idle consumption. |
Use Scenario: Isolating USB OTG accessory ports in dual-mode tablets to prevent battery drain when no peripheral is attached. IC Role / Device Role / Timing Role: Reverse-current blocker (IROCP = 400 mA) and fast-discharge switch (tDIS = 0.4 ms) activated on detach detection. Use Value: Blocks 5 V backfeed from OTG accessories into tablet battery while ensuring <100 ms port deactivation - critical for UL 62368-1 safety certification. |
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 |
|---|---|---|---|
| TPS22915DBVR | Lower RDS(ON) (28 mΩ), but no reverse-voltage protection or integrated discharge; requires external pull-up on FAULT. | Lacks reverse-current blocking - unsuitable for USB OTG or multi-rail backfeed scenarios. | Select when lowest conduction loss is primary and reverse protection is handled elsewhere in system. |
| RT9711CGQW | Higher current rating (3.6 A), but slower rise time (4.5 ms typ.) and no deglitch on FLAG; RoHS-compliant but not halogen-free. | Slower turn-on increases inrush risk into 120 μF SSD caps; lacks 6 ms blanking - prone to false FLAG asserts. | Prefer for cost-sensitive industrial rails where USB timing compliance is not required. |
Compared with TPS22915DBVR and RT9711CGQW, AP22804ASN-7 uniquely combines USB-grade timing (2.1 ms rise, 6 ms FLAG blanking), reverse-voltage blocking (50 mV trip), and halogen-free Green packaging - making it the only choice for certified consumer USB 3.x and SSD hot-swap designs.

FAQ
What is the function of the NC pin on AP22804ASN-7?
Pin 6 is a no-connect (NC) terminal with no internal bond wire or circuit connection. It is electrically isolated and may be left unconnected or tied to GND solely for mechanical reinforcement or thermal relief - it does not affect electrical performance or protection functionality.
Does AP22804ASN-7 support automatic recovery after over-temperature shutdown?
Yes. When junction temperature exceeds +140 °C, the device disables the power switch and asserts FLG low. After cooling by ≥35 °C (to ~+105 °C), it automatically re-enables - cycling until the thermal fault is removed. This behavior is inherent and requires no external circuitry.
Can AP22804ASN-7 be used with a 3.3 V input supply?
Yes. Its 2.7–5.5 V input range fully covers 3.3 V nominal rails. At VIN = 3.3 V, RDS(ON) remains ≤65 mΩ (max), tR is 1.0–3.5 ms, and UVLO releases at 2.0 V - ensuring reliable operation in 3.3 V SSD and tablet applications.
How does the FLG pin behave during normal operation versus fault conditions?
During normal operation, FLG remains high-impedance (open-drain); an external pull-up resistor sets it to high. It pulls low only after confirmed over-current or over-temperature events survive the 6 ms deglitch window - and stays low until both faults clear and the device recovers.
