Product details
Overview
AP21510FM-7 from Diodes Incorporated is a single-channel, active-high enable, current-limited high-side power switch optimized for USB 2.0-compliant hot-swap applications. It delivers 0.2A continuous load current with 95mΩ typical RDS(ON), 0.4ms typical rise time, and integrated short-circuit/thermal/UVLO protection - deployed in consumer USB ports, docking stations, and portable device power rails.
For engineers reviewing the AP21510FM-7 datasheet, AP21510FM-7 pinout, AP21510FM-7 application, or AP21510FM-7 equivalent, key selection criteria include enable polarity (active-high), thermal shutdown threshold (+140°C), reverse current blocking capability, and U-DFN2018-6 package compatibility with space-constrained PCB layouts.
Technical Context
The AP21510FM-7 integrates a low-RDS(ON) N-channel MOSFET with precision current-sense FET architecture to enforce 400mA typical overcurrent limiting without external components. Its UVLO circuit holds the switch off until VIN ≥1.9V and disables it below that threshold, enabling robust hot-plug sequencing.
Thermal protection uses die-temperature sensing with +140°C trip point and +25°C hysteresis, causing automatic cycling during sustained overload. The active-high EN pin directly interfaces with 3.3V/5V logic, while reverse current blocking prevents backflow when input is unpowered and output remains biased.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit (Typ.) | 400mA - clamps output current during overload to prevent damage to downstream circuitry |
| RDS(ON) (25°C) | 95mΩ - enables <100mV drop at 0.2A, minimizing power loss and self-heating |
| tR (Rise Time) | 0.4ms - controls inrush current during hot-insertion, reducing system-level voltage sag |
| UVLO Threshold | 1.9V (typ.) - ensures switch remains off during brown-out or incomplete power-up sequences |
| Shutdown Current | 1µA (max) - preserves battery life in always-on portable systems when disabled |
| ESD Rating | 15kV IEC 61000-4-2 (air) - withstands real-world ESD events on USB-facing outputs |
| Operating Temp. | −40°C to +85°C - supports industrial-grade operation in consumer electronics enclosures |
Pinout & Package
AP21510FM-7 is housed in a 2.0mm × 1.8mm U-DFN2018-6 package with exposed thermal pad. The package supports high-density routing and requires GND connection of the exposed pad for optimal thermal performance (θJA = 70°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference and thermal path | Primary return for internal circuitry; must be connected to PCB ground plane via vias |
| 2 IN | Power input supply rail | Accepts 2.7–5.5V input; connects to upstream USB VBUS or system rail |
| 3 EN | Active-high enable control | Drives high (>2V) to turn on; low (<0.8V) disables output and reduces quiescent current to ≤1µA |
| 4 NC | No internal connection | Unbonded pad - must be left floating or tied to GND per layout best practice |
| 5,6 OUT | Switched power output | Delivers controlled voltage to load; pins 5 and 6 are internally paralleled for lower resistance |
Key Features
| Feature | Design Value |
|---|---|
| Active-High Enable Logic | Direct interface with 3.3V/5V microcontroller GPIO without level-shifting or inversion |
| Reverse Current Blocking | Prevents backfeed from powered output to unpowered input - critical for dual-power domain isolation |
| Controlled Rise/Fall Times | 0.4ms tR/0.04ms tF - limits dI/dt-induced noise and eliminates need for external slew-rate control |
| Integrated Thermal Shutdown | +140°C trip with +25°C hysteresis - enables safe auto-recovery during transient overloads without latch-up |
| UL & CB Safety Certification | UL File E322375 and IEC60950-1 CB certified - simplifies end-equipment safety compliance |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side USB power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCK107AG,314 (Toshiba) | 0.5A limit, 65mΩ RDS(ON), active-high EN, same U-DFN2018-6 footprint | Higher current capacity but lacks IEC 61000-4-2 ESD rating and UL certification | Preferred where higher load current is required and safety certifications are not mandated |
| TPS22965DSGT (TI) | 0.6A limit, 42mΩ RDS(ON), active-high EN, WSON-6 (2.0×2.0mm) package | Lower on-resistance improves efficiency but requires different PCB layout; no reverse current blocking | Chosen when minimal voltage drop is critical and reverse current is managed externally |
Compared with TCK107AG and TPS22965, the AP21510FM-7 uniquely combines UL/CB safety certification, 15kV IEC ESD protection, and reverse current blocking in a 2.0×1.8mm footprint - making it optimal for certified consumer USB endpoints where reliability and regulatory compliance are non-negotiable.

FAQ
What is the maximum continuous load current supported by AP21510FM-7?
The AP21510FM-7 is rated for 0.2A continuous load current under recommended operating conditions (−40°C to +85°C, 2.7–5.5V input). Its 400mA typical current-limit threshold provides headroom for transient surges, but sustained operation above 0.2A risks thermal shutdown due to power dissipation in the 95mΩ RDS(ON) switch.
Does AP21510FM-7 require an external capacitor on the output for stability?
Yes - a minimum 10μF electrolytic capacitor is recommended on the OUT pin for heavy loads, and a 0.01–0.1μF ceramic capacitor improves immunity to short-circuit transients. For no-capacitor applications (e.g., MHL/HDMI dual-mode ports), a Schottky diode must be added at OUT to prevent damage during accidental ground shorts.
How does the thermal shutdown feature behave during sustained overload?
When junction temperature reaches +140°C, the AP21510FM-7 disables the output and remains off until temperature drops ~25°C (to ~115°C), then automatically re-enables. This hysteresis-driven cycling continues until the fault is removed - protecting the device without requiring external reset circuitry.
Can AP21510FM-7 be used in automotive applications?
No - the AP21510FM-7 is specified for −40°C to +85°C ambient operation and lacks AEC-Q200 qualification, extended temperature range (−40°C to +125°C), or automotive-specific reliability testing. It is intended for consumer, computing, and industrial equipment, not under-hood automotive systems.
