Product details
Overview
AP22804AM8-13 from Diodes Incorporated is a single-channel, active-high enable, high-side load switch optimized for USB 2.0 hot-swap applications. It features 50 mΩ RDS(ON), 2.7–5.5 V input range, 2.5 A current limit, integrated output discharge, and reverse-voltage protection with 50 mV trip threshold. Used in ultrabook power sequencing and SSD power rail control.
For engineers reviewing the AP22804AM8-13 datasheet, AP22804AM8-13 pinout, AP22804AM8-13 application, or AP22804AM8-13 equivalent, key selection criteria include enable polarity (active-high), thermal shutdown at +140°C, 6 ms FLG deglitch timing, and MSOP-8 package compatibility with PCB layout constraints for high-current switching.
Technical Context
The AP22804AM8-13 integrates an N-channel MOSFET with current-sense FET-based overcurrent detection, eliminating external sense resistors. Its UVLO triggers at 2.0 V with 180 mV hysteresis, ensuring reliable turn-on only after stable input rail establishment.
Thermal protection uses die-temperature sensing with +140°C shutdown and +35°C hysteresis, enabling auto-recovery cycling during sustained overload. The open-drain FLG pin reports both overcurrent and overtemperature faults after a fixed 6 ms deglitch window to suppress transient false triggers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports full USB 2.0 bus voltage tolerance and 3.3 V/5 V system rails. |
| RDS(ON) | 50 mΩ (typ) - enables ≤125 mW conduction loss at 2.5 A, reducing thermal stress in MSOP-8 package. |
| Current Limit | 3.0 A (max) - clamps output during short-circuit while maintaining safe junction temperature under continuous fault. |
| FLG Blanking Time | 6 ms (typ) - prevents false fault reporting during capacitive inrush or transient load spikes without external RC filtering. |
| Reverse-Voltage Trip | 50 mV (typ) - blocks reverse current when VOUT exceeds VIN by ≥50 mV for ≥6 ms, protecting upstream supplies. |
| Output Discharge Resistance | 115 Ω (typ) - discharges 1 µF output capacitance to <0.5 V in ≤0.4 ms upon disable, preventing floating rail issues. |
| Thermal Shutdown Threshold | +140 °C - activates automatic shutdown before silicon damage; +35 °C hysteresis ensures stable recovery. |
Pinout & Package
AP22804AM8-13 is housed in a thermally enhanced MSOP-8 package with exposed pad (recommended to connect to GND for improved power dissipation). Pin assignments are validated per Diodes DS39137 Rev. 3-2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Switched output node; connects to load and 0.1 µF + ≥10 µF bypass capacitors for USB-compliant hot-swap stability. |
| 2 | GND | Power ground reference; must be low-impedance connection to PCB ground plane for thermal and noise performance. |
| 3 | FLG | Open-drain fault flag; pulls low after 6 ms deglitch on overcurrent or overtemperature; requires external pull-up. |
| 4 | EN | Active-high enable input; logic high ≥1.5 V enables switch; logic low ≤0.65 V disables switch and activates discharge path. |
| 5 | IN | Input power rail; requires 1 µF X7R ceramic capacitor placed adjacent to pin to suppress supply transients. |
| 6–7 | IN | Dual-input pins internally paralleled to reduce trace inductance and improve current sharing in high-dI/dt paths. |
| 8 | NC | No internal connection; must remain unconnected or tied to GND per layout best practice (no functional impact). |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft-start | 0.6 ms typical rise time limits inrush current to ≤2.5 A during hot-plug, avoiding input rail collapse. |
| Integrated output discharge | 115 Ω internal discharge path ensures rapid, controlled VOUT decay (<0.4 ms for 1 µF), eliminating floating-rail latch-up. |
| Reverse-current blocking | 50 mV comparator + 6 ms timer prevents backfeed from downstream loads, protecting host supplies in shared-rail systems. |
| Auto-recovery protection | Overcurrent, short-circuit, and overtemperature faults trigger self-resetting cycles-no manual reset required. |
| UVLO with hysteresis | 2.0 V turn-on / 1.82 V turn-off threshold prevents erratic switching near brown-out conditions. |
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 |
|---|---|---|---|
| TPL7407LDR | 7-channel, 500 mA per channel, no reverse-voltage protection, 150 mΩ RDS(ON). | Targeted at low-power GPIO-driven loads (LEDs, relays); unsuitable for USB hot-swap or >1 A loads. | Select only for multi-load, low-current digital I/O buffering-not for single-rail power distribution. |
| TPS22915BYFPR | Single-channel, 2 A, 44 mΩ RDS(ON), active-low enable, no integrated discharge, 100 mV reverse-voltage threshold. | Lacks output discharge and has higher reverse-voltage trip, requiring external circuitry for USB-compliant hot-swap. | Prefer when board space is constrained (0.9 mm × 1.3 mm DSBGA) and discharge is handled externally. |
Compared with TPL7407LDR and TPS22915BYFPR, AP22804AM8-13 uniquely combines USB-optimized 6 ms FLG deglitch, integrated discharge, and 50 mV reverse-voltage blocking in a manufacturable MSOP-8 footprint-enabling robust hot-swap without design compromises.

FAQ
What is the maximum continuous output current supported by AP22804AM8-13?
The AP22804AM8-13 is rated for 2.5 A continuous output current under recommended operating conditions (VIN = 2.7–5.5 V, TA ≤ +85°C, with proper PCB thermal design). Its overcurrent limit is 3.0 A (typ), and short-circuit current is 0.45 A (typ), both with auto-recovery behavior. Exceeding 2.5 A continuously risks thermal shutdown unless board-level heatsinking is enhanced.
Does AP22804AM8-13 require external components for basic operation?
No external components are required for core functionality: IN and OUT must each have dedicated ceramic bypass capacitors (1 µF at IN, 0.1 µF + ≥10 µF at OUT), and FLG requires a pull-up resistor. The device integrates soft-start, discharge, UVLO, and 6 ms deglitch-eliminating need for external timers, MOSFET drivers, or current-sense resistors.
How does the reverse-voltage protection function in AP22804AM8-13?
AP22804AM8-13 monitors the differential voltage (VOUT − VIN). If this exceeds +50 mV for ≥6 ms, the internal MOSFET turns off to block reverse current. Recovery occurs automatically when the condition clears. This protects upstream supplies from backfeed in shared-rail or battery-backup configurations without external diodes.
Can AP22804AM8-13 be used in automotive applications?
AP22804AM8-13 is not AEC-Q200 qualified and operates only from −40°C to +85°C ambient. While its electrical specs meet some infotainment subsystem requirements, Diodes Incorporated does not specify it for automotive use. For automotive-grade load switching, consider Diodes' AP22916Q or similar AEC-Q100 qualified alternatives.
