Product details
Overview
AP22815AWT-7 from Diodes Incorporated is a 3A, single-channel, high-side power distribution switch with integrated output overvoltage protection (OVP), USB PD3.0 fast role-swap support, and 40mΩ RDS(ON). It operates from 3.0V to 5.5V input, delivers 2.1ms typical soft-start rise time, and provides auto-recovering overcurrent, short-circuit, overtemperature, and reverse-current protection. It is optimized for USB hot-swap and load switching in ultrabooks and SSDs.
For engineers reviewing the AP22815AWT-7 datasheet, AP22815AWT-7 pinout, AP22815AWT-7 application, or AP22815AWT-7 equivalent, key selection criteria include its 7ms FLG deglitch timeout, 5.7V OVP trip threshold, 110µs VOUT recovery during USB PD fast role-swap, and TSOT25 package compatibility with discharge circuitry on the OUT pin.
Technical Context
The AP22815AWT-7 implements a thermally robust N-channel MOSFET high-side switch with integrated current-sense FET architecture-eliminating external sense resistors-and features a dedicated voltage-sense path for precise 5.7V ±0.2V OVP lockout with 100ns response time. Its UVLO activates at 2.5V with 180mV hysteresis and disables the switch below 2.1V.
It integrates a 7ms deglitch timer on the open-drain FLG output to suppress false fault reporting during capacitive inrush, and includes internal discharge circuitry tied directly to the OUT pin-enabling automatic residual voltage bleed-down without external components when disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - supports full USB 2.0/3.x and USB PD bus voltage compliance. |
| RDS(ON) | 40mΩ typ - enables ≤120mW conduction loss at 3A, reducing thermal stress in TSOT25. |
| OVP Trip Threshold | 5.7V ±0.2V - clamps output before USB 5V tolerance violation (5.25V–5.5V) causes downstream damage. |
| Fast Role-Swap Recovery | ≤110µs - restores VOUT to valid USB range (4.75–5.25V) after polarity reversal, meeting USB PD3.0 timing. |
| FLG Blanking Time | 7ms typ - prevents false fault latching during transient inrush into heavy capacitive loads (e.g., 100µF SSD rails). |
| Thermal Shutdown | +140°C with +35°C hysteresis - enables safe cycling under sustained overload without permanent latch-off. |
| Reverse-Voltage Trip | 65mV - blocks reverse current flow when VOUT exceeds VIN, protecting upstream sources during hot-plug disconnect. |
Pinout & Package
AP22815AWT-7 is housed in a RoHS-compliant, green TSOT25 (SOT-25) 5-pin surface-mount package measuring 2.9mm × 1.6mm × 0.8mm, with exposed thermal pad for enhanced heat dissipation (RθJA = 85°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Switched Output Terminal | High-side power output with integrated discharge FET; sinks residual charge from 100µF+ loads when EN is low. |
| 2: GND | Power & Signal Ground Reference | Common return path for internal current sensing, thermal monitoring, and FLG pull-down. |
| 3: FLG | Open-Drain Fault Indicator | Active-low signal asserting after 7ms deglitch on OCP, OTP, or OVP; requires external pull-up for system interrupt. |
| 4: EN | Enable Control Input | Logic-compatible input supporting active-high or active-low configuration; must not float per design requirements. |
| 5: IN | Input Power Supply Terminal | Main power rail connection (3.0–5.5V); bypassed internally and externally to suppress VIN transients during hot-swap. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Discharge Path on OUT | Eliminates need for external bleed resistor; discharges 100µF load to <1V within 10ms when disabled. |
| USB PD3.0 Fast Role-Swap Support | VOUT recovers to 4.75V within 110µs after VOUT collapse, enabling seamless DFP/UFP role transition. |
| Auto-Recovering Protection Suite | OVP, OCP, SCP, OTP, and reverse-current faults self-clear once condition normalizes-no reset required. |
| 7ms FLG Deglitch Timer | Hardware-based blanking prevents false interrupts during inrush into 100µF+ capacitive loads. |
| Reverse-Voltage Blocking at 65mV | Prevents backfeed from powered peripherals (e.g., USB devices) into host supply during disconnect. |

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 |
|---|---|---|---|
| AP22615W6-7 | TSOT26 package; includes ISET pin for adjustable 0.4–4.0A current limit via external resistor. | Required where programmable OCP is needed (e.g., multi-rail systems with varying load profiles). | Select AP22615W6-7 only if adjustable current limit is mandatory; AP22815AWT-7 offers fixed 3.6A limit and smaller TSOT25 footprint. |
| TCK107AG,TL | Toshiba part; 36mΩ RDS(ON), 5.5V OVP, but lacks USB PD fast role-swap and reverse-voltage blocking. | Suitable for basic hot-swap where USB PD compliance and reverse-current blocking are not required. | Choose TCK107AG,TL only for cost-sensitive non-USB applications; AP22815AWT-7 adds critical USB PD3.0 and reverse-protection features. |
Compared with AP22615W6-7, AP22815AWT-7 saves PCB area and simplifies layout with fixed OCP and TSOT25 size, while compared with TCK107AG,TL, it delivers certified USB PD3.0 timing, 65mV reverse-blocking, and integrated discharge-critical for modern portable and embedded USB systems.

FAQ
What is the purpose of the 7ms deglitch timeout on the FLG pin?
The 7ms deglitch timeout prevents false fault assertions caused by transient inrush currents when powering large capacitive loads (e.g., 100µF SSD rails). It ensures FLG only asserts after sustained overcurrent, overvoltage, or overtemperature conditions exceed this window-eliminating need for external RC filtering or firmware debouncing.
Does AP22815AWT-7 support both active-high and active-low enable configurations?
Yes-EN pin supports either logic polarity: applying ≥1.2V enables the switch (active-high), while ≤0.4V disables it (active-low). The device does not require external level-shifting; GPIO-compatible control is achieved directly, and EN must never be left floating per datasheet requirement.
How does the reverse-voltage protection function in AP22815AWT-7?
The device monitors VOUT–VIN differential and disables the internal MOSFET when reverse voltage exceeds 65mV, preventing backfeed from powered peripherals into the host supply. Below 65mV, reverse current is limited to ~350mA; above it, the switch turns off within 1µs to protect upstream circuitry during hot disconnect.
Can AP22815AWT-7 be used in place of AP22615W6-7 without redesign?
No-AP22815AWT-7 uses TSOT25 (5-pin) while AP22615W6-7 uses TSOT26 (6-pin) with an additional ISET pin for adjustable current limiting. Pinout, footprint, and OCP configurability differ; substitution requires PCB revision and validation of fixed 3.6A limit versus system load requirements.
