Product details
Overview
AP22818AM8-13 from Diodes Incorporated is a 2.0A single-channel high-side load switch optimized for USB and hot-swap applications, featuring 75mΩ RDS(ON), 2.7V–5.5V input range, integrated output discharge, reverse-current blocking, and auto-recovery overcurrent/overtemperature protection in an MSOP-8 package.
For engineers reviewing the AP22818AM8-13 datasheet, AP22818AM8-13 pinout, AP22818AM8-13 application, or AP22818AM8-13 equivalent, this device delivers controlled power sequencing, short-circuit robustness, and fault-flag reporting without external components-critical for notebook, SSD, and telecom power rail management.
Technical Context
The AP22818AM8-13 integrates an N-channel MOSFET with current-sense FET architecture to enable precise 2.0A overcurrent limiting (typ. 2.7A at 4.5V) and fast short-circuit response. Its thermal shutdown triggers at +150°C with +40°C hysteresis, enabling safe cycling under sustained overload.
It implements a 6ms deglitch timeout on the open-drain FLG pin to suppress false fault reporting during capacitive inrush, while its built-in soft-start achieves 2.1ms typical rise time (CL = 4.7μF, RLOAD = 10Ω) and supports both active-high and active-low enable variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current Rating | 2.0A continuous - supports high-capacitance USB loads and SSD power rails without derating at +85°C ambient. |
| RDS(ON) | 75mΩ typ. at 5V - minimizes conduction loss (≤75mW at 1A), enabling compact thermal design in MSOP-8. |
| Input Voltage Range | 2.7V to 5.5V - compatible with 3.3V and 5V system rails, including USB 2.0/3.0 VBUS and embedded I/O domains. |
| UVLO Threshold | 2.3V typ. with 180mV hysteresis - prevents erratic turn-on during brown-out and ensures clean hot-plug insertion. |
| FLG Blanking Time | 6ms typ. - eliminates false overcurrent flags during capacitor charging transients, removing need for external RC filtering. |
| Discharge Resistance | 140Ω typ. - actively discharges output capacitance to <0.5V in ≤0.4ms when disabled, preventing backfeed and latch-up. |
| Reverse-Voltage Trip | 70mV typ. - blocks reverse current flow when VOUT exceeds VIN by ≥70mV, protecting upstream sources. |
Pinout & Package
AP22818AM8-13 is housed in a thermally efficient, RoHS-compliant MSOP-8 package (3.0mm × 3.0mm × 1.1mm) with matte tin-plated leads solderable per MIL-STD-202 Method 208 (e3). Pin 1 is marked with a dot; pin numbering follows standard MSOP convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference for internal circuitry and thermal path; must be connected to low-impedance PCB ground plane. |
| 2 | IN | Input voltage supply pin; requires 1μF ceramic bypass capacitor placed adjacent to minimize input ringing. |
| 3 | FLG | Open-drain fault flag (active-low); asserts after 6ms deglitch upon overcurrent or overtemperature event. |
| 4 | EN | Active-high enable input; logic high ≥1.5V enables switch; must not float-tie to GND or controller GPIO. |
| 5 | OUT | Switched output; connects to load and requires 0.1μF ceramic + ≥10μF bulk capacitor for USB compliance and transient immunity. |
| 6–8 | OUT / OUT / GND | Multiple OUT pins (6,7) and additional GND (8) provide parallel current paths and enhanced thermal dissipation in MSOP-8 layout. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 140Ω internal discharge FET reduces VOUT to <0.5V in 0.4ms-eliminates need for external bleed resistor in space-constrained designs. |
| Auto-Recovery Protection | Overcurrent, short-circuit, and overtemperature faults self-clear once condition resolves-no manual reset required for system resilience. |
| Reverse-Current Blocking | Prevents backflow from VOUT to VIN when VOUT > VIN + 70mV-essential for multi-rail systems and battery backup isolation. |
| Controlled Rise Time | 2.1ms typical turn-on (CL = 4.7μF) limits inrush current to prevent input rail droop and avoid tripping upstream current limiters. |
| 6ms Fault Blanking | Hardware-based deglitch on FLG pin rejects transient overloads (e.g., capacitor charging spikes), ensuring reliable host MCU interrupt handling. |
Applications
| USB 3.0 Port Power Switching | SSD Power Sequencing |

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 |
|---|---|---|---|
| TPS22916BQDBVR | 1.5A rating, 85mΩ RDS(ON), no integrated discharge FET, 1.8V–5.5V input range. | Lacks output discharge and reverse-voltage protection; requires external resistor for discharge path. | Choose when lower cost and smaller footprint (SOT-23-5) outweigh need for autonomous discharge and reverse blocking. |
| RT9711CGJ5 | 2.5A rating, 55mΩ RDS(ON), no FLG pin, no deglitch, no reverse-voltage comparator. | Provides higher current but no fault reporting or reverse protection-requires external monitoring circuitry. | Prefer for high-current, non-fault-critical rails where simplicity and low RDS(ON) dominate over diagnostics and safety features. |
Compared with TPS22916BQDBVR and RT9711CGJ5, AP22818AM8-13 uniquely combines 2.0A capability, integrated discharge, reverse-current blocking, and deglitched FLG reporting in a single MSOP-8 package-making it optimal for USB, SSD, and telecom applications demanding full autonomous protection.

FAQ
What is the maximum continuous output current supported by AP22818AM8-13?
The AP22818AM8-13 is rated for 2.0A continuous output current under recommended operating conditions (TA ≤ +85°C, VIN = 2.7V–5.5V). Its overcurrent limit is specified at 2.7A typ. at VOUT = 4.5V, with thermal shutdown engaging at +150°C junction temperature to ensure safe operation during sustained overload.
Does AP22818AM8-13 require external components for output discharge or fault debouncing?
No. AP22818AM8-13 integrates a 140Ω discharge FET that actively pulls the output to <0.5V within 0.4ms when disabled, eliminating the need for external resistors. Its 6ms hardware deglitch on the FLG pin also removes requirement for external RC filters to suppress false overcurrent interrupts during capacitive inrush.
How does AP22818AM8-13 handle reverse voltage conditions?
The device monitors VOUT – VIN and disables the internal MOSFET when the difference exceeds 70mV (typ.) for 6ms. This blocks reverse current flow from output to input, protecting upstream supplies in multi-rail systems-without requiring external diodes or controllers.
Can AP22818AM8-13 be used in automotive applications?
AP22818AM8-13 is not AEC-Q100 qualified. While it operates across –40°C to +85°C and meets IEC60950-1 CB certification, Diodes Incorporated explicitly states that automotive-grade versions (with PPAP, change control, and IATF 16949 manufacturing) require direct engagement with their automotive team-this part is intended for commercial/industrial use only.
