Product details
Overview
AP22802BW5-7 from Diodes Incorporated is a single-channel, active-low enable, current-limited high-side load switch in SOT25 package, designed for USB and hot-swap applications. It delivers 2.7–5.5V input operation, 50 mΩ typical RDS(ON) at 5V, 2.7A over-current limit, 0.7µs short-circuit response, and integrated output discharge with 90Ω discharge resistance.
For engineers reviewing the AP22802BW5-7 datasheet, AP22802BW5-7 pinout, AP22802BW5-7 application, or AP22802BW5-7 equivalent, key selection criteria include enable polarity (active-low), thermal shutdown threshold (+140°C), UVLO (2.0V typ), FLG deglitch timing (6ms), and reverse current blocking capability.
Technical Context
The AP22802BW5-7 implements a thermally protected N-channel MOSFET high-side switch with internal current sensing via sense-FET architecture-eliminating external shunt resistors. Its control logic includes under-voltage lockout (UVLO) with 75mV hysteresis and a dedicated open-drain FLG output that asserts low after 6ms deglitch upon over-current or over-temperature events.
It integrates a controlled turn-on rise time (2.1ms typ at 3.3V), fast short-circuit response (0.7µs), and automatic recovery from over-current/short-circuit/over-temperature faults. The device supports heavy capacitive loads up to 470µF and provides reverse current blocking when disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports standard USB 3.3V/5V rails and ensures reliable operation across portable and embedded power domains. |
| RDS(ON) | 50 mΩ (typ @ 5V, 2A) - enables low conduction loss and minimal self-heating during 2A continuous load operation. |
| Over-Current Limit | 2.7A (typ) - clamps output current to protect downstream circuitry during sustained overload without immediate shutdown. |
| Short-Circuit Response Time | 0.7 µs - detects and limits fault current before energy dissipation damages the switch or load. |
| FLG Deglitch Timeout | 6 ms - suppresses false flag assertions caused by transient inrush or capacitive load charging spikes. |
| Discharge Resistance | 90 Ω - provides controlled VOUT discharge to <0.5V within 0.4ms (CL = 1µF), eliminating floating voltage on hot-unplug. |
| Thermal Shutdown Threshold | +140°C - initiates auto-cycling protection under prolonged short-circuit or overload, with +60°C hysteresis for stable recovery. |
Pinout & Package
SOT25 (Green, RoHS-compliant) package with 9 mm² footprint, 180°C/W junction-to-ambient thermal resistance, and optimized pad layout per Diodes Inc. specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT | Switched Output Node | Drives load; features integrated discharge path and reverse current blocking when disabled. |
| 2 GND | Power Ground Reference | Common return for internal circuitry and thermal path; must be connected to low-impedance system ground plane. |
| 3 FLG | Open-Drain Fault Flag | Active-low signal indicating over-current or over-temperature event after 6ms deglitch; requires external pull-up. |
| 4 EN | Enable Input (Active-Low) | Logic-low (≤0.5V) enables switch; logic-high (≥1.5V) disables it; not floating-tolerant. |
| 5 IN | Input Power Supply | Accepts 2.7–5.5V supply; includes UVLO (2.0V rising threshold) to prevent erratic turn-on during brownout. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 90Ω internal discharge FET ensures safe VOUT collapse (<0.5V in 0.4ms) without external components. |
| Auto-Recovery Protection | Over-current, short-circuit, and over-temperature faults trigger current limiting or thermal cycling-not latch-off-enabling resilient system behavior. |
| Reverse Current Blocking | Prevents backflow from VOUT to VIN when disabled, critical for multi-rail systems and USB OTG applications. |
| UVLO with Hysteresis | 2.0V turn-on / 1.925V turn-off threshold prevents oscillation during input ramp-up or brownout conditions. |
| No External Components Required | 6ms FLG deglitch, discharge path, current sensing, and thermal shutdown are fully internal-reducing BOM count and PCB area. |
Applications
| USB Port Power Control | SSD Power Sequencing |
|---|---|
|

| Notebook System Rails | Set-Top Box Peripherals |
|
Use Scenario: Isolating auxiliary rails (e.g., Wi-Fi module, camera, audio codec) in thin-and-light notebooks with strict thermal budgets. IC Role / Device Role / Timing Role: Thermally robust high-side switch with +140°C shutdown and +60°C hysteresis for sustained fault tolerance.

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 |
|---|---|---|---|
| AP22811W5-7 | Active-high enable, identical RDS(ON), UVLO, and protection features; same SOT25 package. | Requires GPIO logic inversion for enable control; otherwise drop-in compatible in new designs targeting active-high signaling. | Select when system MCU outputs active-high enable signals and no level-shifting is desired. |
| TCK107AG,LF | Lower RDS(ON) (28 mΩ), higher ILIMIT (3.5A), but no integrated discharge and 10ms FLG deglitch. | Lacks output discharge function-requires external resistor/capacitor network for VOUT collapse; less suitable for hot-unplug safety. | Choose for higher current capacity and lower conduction loss where discharge is handled externally or unnecessary. |
Compared with AP22802BW5-7, AP22811W5-7 offers identical performance with inverted enable polarity, while TCK107AG,LF trades discharge integration and tighter deglitch for lower RDS(ON) and higher current rating-making each optimal for distinct control architecture or thermal/power priorities.

FAQ
What is the enable polarity of AP22802BW5-7?
The "B" suffix denotes active-low enable: the device turns ON when EN is pulled ≤0.5V and turns OFF when EN is ≥1.5V. This matches microcontroller GPIOs configured for active-low drive without external inverters. Leaving EN floating is prohibited and may cause unpredictable switching behavior.
Does AP22802BW5-7 provide reverse current blocking?
Yes-it blocks reverse current from OUT to IN when disabled, with IREV limited to 1µA max at VOUT = 5V and VIN = 0V. This prevents back-powering of upstream supplies in multi-rail systems and is essential for USB OTG and battery-backed subsystems.
How does the FLG pin behave during a short-circuit event?
Upon detecting over-current or over-temperature, FLG goes low after a fixed 6ms deglitch period and remains low until both faults are cleared. During thermal cycling, FLG stays asserted low throughout repeated shutdown/recovery cycles, providing unambiguous system-level fault indication without external timing components.
Can AP22802BW5-7 drive a 470µF output capacitor safely?
Yes-the device is characterized for CL = 470µF in its datasheet waveforms and supports controlled turn-on (2.1ms rise time) and fast short-circuit response (0.7µs). Its integrated current limiting prevents destructive inrush, and the discharge function actively collapses VOUT when disabled-even with no load present.
