Product details
Overview
AP22811BM8-13 from Diodes Incorporated is a single-channel, current-limited, high-side power distribution load switch optimized for USB and hot-swap applications. It features 50 mΩ RDS(ON), 2.7–5.5 V input range, integrated output discharge, reverse-voltage protection (50 mV trip), and 6 ms deglitched FLG fault reporting - enabling robust power control in ultrabooks and SSDs.
For engineers reviewing the AP22811BM8-13 datasheet, AP22811BM8-13 pinout, AP22811BM8-13 application, or AP22811BM8-13 equivalent, key selection criteria include enable polarity (Active Low), thermal shutdown threshold (+140°C), soft-start rise time (2.1 ms typ.), and MSOP-8 package compatibility with high-density PCB layouts.
Technical Context
The AP22811BM8-13 implements an N-channel MOSFET high-side switch with integrated current sensing, UVLO (2.0 V rising), and thermal foldback. Its 6 ms FLG deglitch window suppresses false over-current triggers during capacitive inrush, while reverse-voltage detection disables the switch when VOUT exceeds VIN by ≥50 mV for ≥6 ms.
It delivers auto-recovering over-current (2.7 A typ. limit), short-circuit (0.3 A), and over-temperature protection, with controlled turn-on (tR = 2.1 ms) and fast turn-off (tF = 0.65 ms). The device supports both USB-compliant hot-plug sequencing and reverse-current blocking without external components.
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.) at 5 V - minimizes conduction loss and self-heating under 2 A continuous load in MSOP-8 package. |
| Output Current Limit | 2.7 A (typ.) - provides safe current clamping during overload without latch-off, enabling auto-recovery. |
| FLG Blanking Time | 6 ms (typ.) - prevents false fault assertion during transient inrush into heavy capacitive loads (e.g., 120 µF SSD rails). |
| Reverse-Voltage Trip | 50 mV (typ.) - blocks reverse current flow when VOUT > VIN, protecting upstream supplies in shared-rail systems. |
| Thermal Shutdown | +140 °C (typ.) with +35 °C hysteresis - enables safe cycling during sustained short-circuit faults without permanent disable. |
| Discharge Resistance | 90 Ω (typ.) - actively discharges output capacitance to <0.5 V within 0.4 ms after disable, preventing floating rail issues. |
Pinout & Package
AP22811BM8-13 is housed in a thermally efficient, RoHS-compliant MSOP-8 package (3.0 mm × 3.0 mm × 1.1 mm), rated for 165 °C/W junction-to-ambient thermal resistance on standard FR-4 PCBs.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | IN | Voltage input pin - requires 1 µF low-ESR ceramic capacitor to GND for stable regulation and noise immunity. |
| 4 | EN/EN | Active-Low enable input - logic low ≤0.5 V enables switch; must not float; ties directly to GPIO or pull-down resistor. |
| 5 | FLG | Open-drain fault flag - active-low signal asserted after 6 ms deglitch upon over-current or over-temperature event. |
| 6, 7, 8 | OUT | Switched output pin - connects to load and requires 0.1 µF + ≥100 µF bulk capacitance for hot-swap stability and short-circuit energy absorption. |
| 1 | GND | Ground reference for internal circuitry and power path - must be low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in Soft-Start | 0.6 ms typical rise time - eliminates inrush current spikes into large output capacitors (e.g., 120 µF SSD rails). |
| Integrated Output Discharge | 90 Ω discharge path - ensures rapid, controlled VOUT decay to <0.5 V within 0.4 ms, preventing backfeed or latch-up. |
| Reverse-Voltage Protection | 50 mV comparator threshold - blocks reverse current before damaging upstream regulators or shared-bus systems. |
| Auto-Recovering Protections | Over-current, short-circuit, and over-temperature all recover automatically once fault clears - no manual reset required. |
| UL & CB Certification | UL Recognized (E322375) and IEC60950-1 CB certified - meets safety requirements for commercial and industrial end equipment. |
Applications

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 |
|---|---|---|---|
| AP22811AM8-13 | Identical specs except Active-High EN/EN pin logic (vs. Active-Low in BM8-13) | Requires inverted enable signal routing; same thermal, electrical, and layout footprint | Select when system GPIO drives enable high to activate power - avoids external inverter logic. |
| TCK112G,LF | Lower RDS(ON) (25 mΩ), higher ILIMIT (4.5 A), but no reverse-voltage protection or integrated discharge | Suited for high-current, non-reverse-sensitive rails; requires external discharge circuit for hot-swap | Choose for higher efficiency at >2 A loads where reverse blocking is handled elsewhere in system design. |
Compared with AP22811AM8-13, the BM8-13 simplifies enable interface in low-active control architectures; versus TCK112G, it trades lower conduction loss for integrated protection features critical in USB and portable applications.

FAQ
What is the enable polarity of AP22811BM8-13?
The "B" suffix denotes Active-Low enable functionality: the device turns ON when the EN/EN pin voltage is ≤0.5 V and turns OFF when ≥1.5 V. This matches common microcontroller GPIO low-active outputs without level-shifting or inversion circuitry.
Does AP22811BM8-13 require external components for basic operation?
No external components are required for core switching and protection functions. However, per datasheet recommendations, a 1 µF ceramic capacitor must be placed between IN and GND, and a 0.1 µF + ≥100 µF capacitor between OUT and GND to ensure stable hot-swap performance and prevent input ringing during short-circuit events.
How does the FLG pin behave during a short-circuit event?
Upon detecting over-current or over-temperature, the open-drain FLG pin pulls low after a 6 ms deglitch timeout and remains low until both fault conditions clear. During recovery, FLG returns high only after output current normalizes and junction temperature falls below the hysteresis threshold (~105 °C).
Can AP22811BM8-13 be used in automotive applications?
The AP22811BM8-13 is not AEC-Q100 qualified and is intended for commercial/industrial use. Diodes Incorporated offers automotive-grade variants (e.g., AP22811Q series) with PPAP support, IATF 16949 manufacturing, and extended temperature validation - contact Diodes sales for qualified alternatives.
