Product details
Overview
AP22815BWT-7 from Diodes Incorporated is a 3A, single-channel, high-side power distribution switch with output overvoltage protection (OVP), USB PD3.0 fast role-swap support, 40mΩ RDS(ON), and integrated discharge circuitry in TSOT25 package. It delivers precise current limiting for USB hot-swap, SSD power sequencing, and ultrabook load switching applications.
For engineers reviewing the AP22815BWT-7 datasheet, AP22815BWT-7 pinout, AP22815BWT-7 application, or AP22815BWT-7 equivalent, key selection criteria include OVP trip at 5.7V ±0.2V, 7ms FLG deglitch timeout, 2.1ms typical soft-start rise time, and thermal shutdown at +140°C with +35°C hysteresis.
Technical Context
The AP22815BWT-7 implements a thermally robust N-channel MOSFET high-side switch with integrated voltage sense, current sense, and thermal monitoring blocks. Its OVP comparator triggers at 5.7V with 100mV hysteresis and responds within 1µs, while short-circuit detection activates in ≤5µs with auto-recovery.
It supports both active-high and active-low EN logic, features undervoltage lockout (UVLO) at 2.5V (rising) with 180mV hysteresis, and provides reverse-voltage blocking at 65mV differential (VOUT – VIN). The internal discharge path on OUT enables safe capacitive load discharge when disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - supports full USB 3.3V/5V bus operation without external regulation |
| RDS(ON) | 40mΩ typ @ 5V - enables 3A continuous output with <120mW conduction loss at full load |
| OVP Threshold | 5.7V ±0.2V - clamps transient overvoltage before damage to downstream 5V-tolerant ICs |
| Fast Role-Swap Recovery | <110µs - restores valid USB voltage (≥4.75V) after polarity reversal per USB PD3.0 spec |
| Thermal Shutdown | +140°C with +35°C hysteresis - prevents latch-up during sustained overload; enables self-resetting fault recovery |
| FLG Blanking Time | 7ms typ - suppresses false fault reporting during inrush or heavy capacitive load turn-on |
| Reverse-Voltage Trip | 65mV (VOUT – VIN) - blocks reverse current before backfeed damages upstream supplies |
Pinout & Package
AP22815BWT-7 is housed in a RoHS-compliant, green TSOT25 (SOT-25) 5-pin surface-mount package measuring 2.9mm × 1.6mm × 1.1mm, optimized for high thermal efficiency (RΘJA = 85°C/W) and space-constrained USB/SSD designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Switched Output Node | Drives load; integrates internal discharge FET to safely bleed 100µF+ output capacitance when disabled |
| 2: GND | Power & Signal Reference | Common return for internal control circuitry, current sense, and thermal sensor; must be low-impedance |
| 3: FLG | Open-Drain Fault Indicator | Active-low signal asserts after 7ms deglitch on OVP, OCP, or OTP; requires external pull-up |
| 4: EN | Enable Control Input | Logic-compatible input supporting active-high (≥1.2V) or active-low (≤0.4V); no floating allowed |
| 5: IN | Power Input Supply | Accepts 3.0–5.5V input; feeds internal LDO and gate driver; requires 1µF local ceramic bypass |
Key Features
| Feature | Design Value |
|---|---|
| Output Overvoltage Protection with Auto-Recovery | Trips at 5.7V, recovers automatically once VOUT falls below 5.6V - eliminates need for external crowbar or reset circuitry |
| Adjustable Current Limit (Fixed in AP22815) | 3.6A typ overload limit - sustains 3A continuous load while clamping surge currents to prevent trace fusing |
| Built-in Soft-Start | 2.1ms typical output rise time - limits inrush di/dt into 100µF+ loads, reducing input rail droop and EMI |
| Integrated Discharge Path on OUT | ~100Ω internal discharge resistance - discharges residual output voltage without external resistor or FET |
| USB PD3.0 Fast Role-Swap Support | <110µs VOUT recovery to ≥4.75V - meets USB Type-C dual-role port timing requirements for seamless power direction reversal |
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 |
|---|---|---|---|
| AP22615WUTBG | TSOT26 package; includes ISET pin for adjustable current limit (0.4–4.0A via resistor) | Supports programmable OCP tuning for multi-rail systems; larger footprint than TSOT25 | Select when design requires field-adjustable current limit or higher thermal margin (RΘJA = 80°C/W) |
| TCK107AG,TL | Toshiba device; 2.7–5.5V range; 30mΩ RDS(ON); no integrated OVP or fast role-swap | Lacks USB PD3.0 compliance and output overvoltage protection - requires external OVP circuit | Choose only if OVP and FRS are not required and lower RDS(ON) is prioritized over protection integration |
Compared with AP22615WUTBG, AP22815BWT-7 offers smaller TSOT25 footprint and fixed 3.6A OCP ideal for cost-sensitive USB ports; versus TCK107AG, it delivers complete protection (OVP, FRS, reverse-block) in one die but trades 10mΩ higher RDS(ON).

FAQ
Does AP22815BWT-7 support both active-high and active-low enable configurations?
Yes. The EN pin accepts either logic-high (≥1.2V) or logic-low (≤0.4V) signals to control output state, with internal hysteresis ensuring noise immunity. No external components are needed to configure polarity - behavior is determined solely by the applied voltage level relative to VIN.
What is the maximum output capacitance the AP22815BWT-7 can safely drive during turn-on?
The device is characterized and qualified to drive ≥100µF output capacitance with controlled 2.1ms rise time and no FLG false triggering, provided the 0.1µF ceramic + 100µF bulk capacitor layout guidelines are followed. Larger values (e.g., 470µF) are supported but require verification of inrush current against 3.6A OCP threshold.
How does the 7ms FLG deglitch function interact with short-circuit events?
The 7ms deglitch timer prevents FLG assertion during brief inrush or capacitive load transients. For true short circuits, FLG asserts only after sustained overcurrent exceeds the 3.6A limit for >7ms - allowing safe startup into heavy loads while still detecting persistent faults that risk thermal damage.
Is external reverse-voltage protection required when using AP22815BWT-7?
No. The device integrates reverse-voltage protection that disables the internal FET when VOUT exceeds VIN by 65mV, preventing backfeed. This eliminates the need for external Schottky diodes or dedicated reverse-current ICs in USB and battery-backup applications.
