Product details
Overview
AP22804BW5-7 from Diodes Incorporated is a single-channel, active-low enable, 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, integrated output discharge, reverse-voltage protection (50 mV trip), and 6 ms deglitched fault flag reporting. It delivers robust protection in ultrabook power sequencing and SSD power rail control.
For engineers reviewing the AP22804BW5-7 datasheet, AP22804BW5-7 pinout, AP22804BW5-7 application, or AP22804BW5-7 equivalent, key selection criteria include active-low EN compatibility, thermal shutdown at +140°C with +35°C hysteresis, UVLO (2.0 V typ), short-circuit recovery behavior, and SOT25 package thermal resistance (123 °C/W).
Technical Context
The AP22804BW5-7 implements an N-channel MOSFET high-side switch with integrated current-sense FET and thermal sensing circuitry. Its protection architecture combines over-current limiting (3.0 A typ ILIMIT), short-circuit clamping (0.45 A typ ISHORT), and auto-recovery thermal shutdown triggered at +140°C junction temperature.
It integrates a dedicated discharge path (90–130 Ω) activated upon disable, reverse-voltage detection (25–75 mV trip), and UVLO with 180 mV hysteresis. The open-drain FLG output includes internal 6 ms deglitching to suppress false triggers during capacitive inrush 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 compliance and wide-system rail compatibility. |
| RDS(ON) | 50 mΩ typ - enables low conduction loss and <125 mW power dissipation at 2.5 A, critical for thermally constrained SOT25 layouts. |
| Output Current Limit | 3.0 A typ (ILIMIT) - provides safe current delivery under overload while maintaining system stability without external current-sense resistors. |
| FLG Blanking Time | 6 ms typ - eliminates false fault reporting during hot-plug inrush or transient capacitive loading without external RC components. |
| Thermal Shutdown Threshold | +140°C with +35°C hysteresis - ensures automatic recovery after fault removal and prevents latch-up during intermittent shorts. |
| Reverse-Voltage Trip | 50 mV typ - blocks reverse current flow when VOUT exceeds VIN by ≥50 mV, protecting upstream supplies in back-fed scenarios. |
| UVLO Threshold | 2.0 V typ with 180 mV hysteresis - prevents erratic switching during brown-out conditions and ensures clean power-up sequencing. |
Pinout & Package
AP22804BW5-7 is housed in a Green SOT25 (SOT-23-5) package with exposed pad recommended for GND connection to improve thermal performance. Pin 1 = IN, Pin 2 = GND, Pin 3 = EN (active-low), Pin 4 = OUT, Pin 5 = FLG.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Power Input | Connects to 2.7–5.5 V supply; requires 1 μF ceramic bypass capacitor placed adjacent to minimize input ringing. |
| 2 (GND) | Ground Reference | Primary ground return for control logic and power path; must be tied to PCB ground plane for thermal and EMI integrity. |
| 3 (EN) | Enable Control | Active-low logic input; driven low ≤0.65 V to enable, high ≥1.5 V to disable; must not float. |
| 4 (OUT) | Switched Output | Delivers controlled power to load; requires 0.1 μF ceramic + ≥10 μF bulk capacitor to ensure stable hot-swap operation. |
| 5 (FLG) | Fault Reporting | Open-drain output asserted low during over-current or over-temperature events after 6 ms deglitch timeout. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in Soft-start | 0.6 ms typical rise time - limits inrush current into heavy capacitive loads (e.g., 120 μF SSD rails) without external timing components. |
| Integrated Output Discharge | 90–130 Ω discharge path - safely drains residual output voltage within 0.4 ms when disabled, preventing floating rail issues. |
| Reverse Current Blocking | 50 mV reverse-voltage trip with 6 ms delay - prevents back-feeding from downstream circuits without diode losses or layout complexity. |
| Auto-Recovery Protection | Over-current, short-circuit, and over-temperature faults all recover automatically once fault condition clears - eliminates manual reset requirement in embedded systems. |
| No External Components Required | 6 ms FLG deglitch, UVLO, discharge, and protection logic are fully integrated - reduces BOM count and PCB area in space-constrained designs. |
Applications
| Ultrabook Power Sequencing | SSD Power Rail Control |
|---|---|
|
Use Scenario: Controlled power-up/down of auxiliary rails (e.g., USB-C PD interface, display backlight) during system resume/suspend cycles. IC Role / Device Role: High-side load switch enabling/disabling 3.3 V or 5 V rails with precise timing and fault isolation. Use Value: Prevents cross-rail contention and inrush-induced voltage droop using soft-start and fast fault response (<6 ms flag assertion). |
Use Scenario: Hot-plug power management for M.2 NVMe SSD modules where sudden insertion must not disrupt host controller stability. IC Role / Device Role: Isolates SSD VCC from main system rail; provides reverse-current blocking and short-circuit immunity during plug-in. Use Value: Eliminates need for external Schottky diode and current-limit resistor, reducing solution size while meeting USB-IF hot-swap compliance. |
| Notebook USB Port Protection | Set-Top Box Peripheral Power Management |
|
Use Scenario: Individual port power control in multi-port USB hubs, isolating faults to prevent system-wide shutdown. IC Role / Device Role: Per-port high-side switch with independent FLG reporting and auto-recovery on over-current events. Use Value: Enables per-port fault logging and graceful degradation - e.g., one failed port does not disable remaining ports. |
Use Scenario: Power gating of HDMI CEC controllers, IR receivers, or USB peripherals in low-power standby mode. IC Role / Device Role: Low-quiescent-current (80 µA typ) load switch that maintains zero-load leakage (<1 µA) when disabled. Use Value: Reduces standby power consumption below 10 µW per switched rail, supporting Energy Star Tier 2 compliance. |
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 |
|---|---|---|---|
| AP22804AW5-7 | Active-high EN instead of active-low; identical RDS(ON), current limit, and protection features. | Requires GPIO logic inversion or pull-up configuration; unsuitable where direct low-active MCU pin drive is preferred. | Select when system control logic uses active-high signaling and no level-shifting is available. |
| TCK112G,LF | Lower RDS(ON) (25 mΩ), higher IOUT (3.5 A), but lacks integrated discharge and reverse-voltage protection. | Requires external 10 kΩ discharge resistor and reverse-blocking diode for equivalent functionality. | Choose only if higher current and lower conduction loss outweigh added BOM cost and board area. |
Compared with AP22804AW5-7, the AP22804BW5-7 simplifies MCU interface by eliminating need for external inverters or pull-ups; compared with TCK112G, it delivers complete protection integration in a smaller footprint despite marginally higher RDS(ON).

FAQ
What is the maximum continuous output current rating for AP22804BW5-7?
The AP22804BW5-7 is rated for 2.5 A continuous output current under recommended operating conditions (VIN = 2.7–5.5 V, TA ≤ +85°C). Its over-current limit is 3.0 A typical, and short-circuit clamp is 0.45 A typical - both with auto-recovery. Derating is required above +70°C ambient due to SOT25 thermal resistance (123 °C/W).
Does AP22804BW5-7 require external components for basic operation?
No external components are required for core switching and protection functions. A 1 μF ceramic capacitor on IN and a 0.1 μF ceramic capacitor on OUT are mandatory for stability and EMI suppression. Bulk capacitance (≥10 μF) on OUT is required for USB/hot-swap compliance but is part of the load-side design, not the IC's functional minimum.
How does the FLG pin behave during a short-circuit event?
Upon detecting over-current or over-temperature, the FLG pin asserts low after a 6 ms deglitch timeout and remains low until both fault conditions clear. During sustained short-circuit, FLG stays low continuously; it does not pulse. Recovery is automatic once load fault is removed and junction temperature falls below +105°C (140°C − 35°C hysteresis).
Can AP22804BW5-7 be used with input voltages below 2.7 V?
No. The absolute minimum input voltage is 2.7 V per Recommended Operating Conditions. Below this, UVLO disables the switch even if EN is asserted, and electrical characteristics (e.g., RDS(ON), ILIMIT) are not guaranteed. Operation below 2.0 V is prohibited - the device enters undervoltage lockout and will not conduct.
