Product details
Overview
AP2162SG-13 from Diodes Incorporated is a dual-channel, active-low enable, current-limited high-side power switch optimized for USB 2.0 hot-swap applications. It delivers 1.5A typical current limiting, 115mΩ on-resistance (MSOP-8EP) / 120mΩ (SO-8), 2.7V–5.5V input range, and integrated short-circuit/thermal protection with 7ms deglitched FLG reporting - deployed in LCD monitors and USB hubs to manage inrush and fault isolation.
For engineers reviewing the AP2162SG-13 datasheet, AP2162SG-13 pinout, AP2162SG-13 application, or AP2162SG-13 equivalent, this page provides verified functional context, SO-8 package mapping, dual-channel enable logic polarity, UVLO threshold (1.9V typ), and real-world hot-plug timing behavior - critical for USB port power sequencing and BOM validation.
Technical Context
The AP2162SG-13 implements two independent high-side MOSFET switches with matched current-limit sensing, UVLO activation at 1.9V (min 1.6V), and thermal shutdown at 140°C with 25°C hysteresis. Each channel features open-drain FLG outputs with 7ms blanking to suppress false triggers from capacitive load inrush.
Its dual active-low EN inputs (EN1/EN2) directly interface with USB host controllers requiring low-asserted enable signals, while reverse-current blocking prevents backfeed from powered downstream loads - essential for self-powered hub compliance and hot-plug safety in consumer electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 1.5A typical - clamps output during overload without external components, sustaining safe operation into short circuits. |
| On-Resistance | 120mΩ max (SO-8, 5V) - limits I²R loss to ≤60mW at 1A, enabling compact thermal design in space-constrained USB ports. |
| Input Voltage Range | 2.7V–5.5V - supports full USB 2.0 bus voltage tolerance and accommodates brown-out conditions down to 2.7V. |
| Rise Time | 0.6ms typical (CL=1µF, RL=10Ω) - controls inrush dv/dt to prevent system rail collapse during hot-insertion. |
| UVLO Threshold | 1.9V typical - ensures switch remains off until stable VIN is established, preventing erratic behavior during power ramp-up. |
| Shutdown Current | 1µA max - minimizes standby drain in battery-backed or always-on USB peripherals. |
| FLG Blanking Time | 7ms typical - filters transient over-current events from bulk capacitor charging, eliminating need for external RC filtering. |
Pinout & Package
AP2162SG-13 is supplied in an SO-8 package with exposed pad (Green compound, RoHS-compliant). The exposed tab must be soldered to PCB ground plane for thermal management but is not rated for electrical conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | Primary return path for internal current sense and thermal sensor; connects to PCB ground plane via exposed pad. |
| 2 IN | Power input | Accepts 2.7V–5.5V supply; feeds both channels; requires local 0.1µF ceramic bypass. |
| 3 EN1 | Channel 1 enable | Active-low logic input; drives high-side switch ON when pulled low (0.8V max VIL). |
| 4 EN2 | Channel 2 enable | Active-low logic input; independent control of second USB port; same VIL/VIH specs as EN1. |
| 5 FLG2 | Channel 2 fault flag | Open-drain output; pulls low after 7ms deglitch upon over-current or over-temperature; requires external pull-up. |
| 6 OUT2 | Channel 2 output | Switched 2.7V–5.5V output; blocks reverse current when disabled; supports up to 1A continuous load. |
| 7 OUT1 | Channel 1 output | Switched 2.7V–5.5V output; electrically isolated from OUT2; reverse-current blocking enabled by internal architecture. |
| 8 FLG1 | Channel 1 fault flag | Open-drain output; identical timing and behavior to FLG2; enables per-port fault diagnostics in multi-port hubs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side switches | Enables discrete control of two USB downstream ports with no cross-talk or shared failure modes. |
| 1.5A accurate current limiting | Guarantees consistent trip point across temperature (-40°C to +85°C), meeting USB 2.0 500mA port compliance with margin. |
| Reverse current blocking | Prevents backfeed from powered peripherals (e.g., USB devices with local batteries) into host VBUS during disconnect. |
| 7ms FLG deglitch | Eliminates false fault reporting during 68µF output capacitor charging, removing need for external timing components. |
| UVLO with 1.9V threshold | Ensures clean power-up sequencing in systems where VBUS ramps slowly, avoiding partial-enable states. |
Applications
| USB 2.0 Dual-Port Hub | LCD Monitor USB Charging Port |
|---|---|
|
Use Scenario: Two downstream USB ports on a desktop monitor providing data + 5V power to peripherals. IC Role / Device Role / Timing Role: High-side power switch managing VBUS delivery per port with independent enable/fault reporting. Use Value: Prevents host controller reset during peripheral hot-plug by limiting inrush to <1.5A and suppressing false over-current flags via 7ms FLG blanking. |
Use Scenario: Dedicated USB-A port on an LCD monitor delivering 500mA charging to smartphones or accessories. IC Role / Device Role / Timing Role: Single-channel power switch (one half of AP2162SG-13) with reverse-current blocking and thermal foldback. Use Value: Blocks backfeed from phone battery into monitor's 5V rail during cable disconnect, enhancing system safety and EMI stability. |
| Set-Top Box Peripheral Port | Gaming Console Accessory Bay |
|

IC Role / Device Role / Timing Role: Hot-swap power controller enforcing USB 2.0 current limits and reporting faults to SoC GPIOs. Use Value: Enables graceful firmware recovery on over-current events instead of uncontrolled rail collapse, improving field reliability. |
Use Scenario: Expansion bay on a gaming console supporting hot-swappable controllers or headsets with USB connectivity. IC Role / Device Role / Timing Role: Dual-channel enable-controlled power gate with controlled 0.6ms rise time for smooth voltage ramp.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel USB power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2172SG-13 | Identical specs except EN inputs are active-high; same SO-8 package, pinout, and FLG behavior. | Requires inverted enable logic from host controller; unsuitable where existing firmware asserts low-enable signals. | Select only if host GPIOs drive high-active enables; otherwise, AP2162SG-13 avoids level-shifting overhead. |
| TUSB2036IPWR | USB 2.0 transceiver + integrated power switch; includes USB PHY, 3.3V LDO, and suspend detection - not a standalone switch. | Replaces entire USB hub IC stack; adds protocol handling but increases BOM cost and layout complexity. | Choose only when full hub functionality (data switching + power control) is required; not a drop-in replacement. |
Compared with AP2172SG-13, AP2162SG-13 eliminates need for external inverters in legacy low-enable systems; versus TUSB2036IPWR, it offers lower cost, smaller footprint, and simpler integration where only power switching-not data routing-is needed.

FAQ
What is the maximum continuous load current per channel for AP2162SG-13?
The recommended maximum continuous load current is 1.0A per channel, as specified in the Absolute Maximum Ratings table and validated under thermal conditions using SO-8 package with θJA = 110°C/W. Exceeding 1.0A risks thermal shutdown at ambient temperatures above 60°C unless board-level heatsinking is enhanced.
Does AP2162SG-13 support reverse-current blocking when disabled?
Yes - the internal high-side MOSFET architecture inherently blocks reverse current flow from OUT to IN when the switch is disabled, verified by IREV ≤ 1µA at VOUT = 5V and VIN = 0V. This prevents backfeed from powered peripherals into the host VBUS rail during hot removal.
Can FLG1 and FLG2 be tied together to a single microcontroller interrupt pin?
Yes - both FLG outputs are open-drain and share identical 7ms deglitch timing. Connecting them to one pull-up resistor and MCU interrupt pin allows consolidated fault detection, provided firmware distinguishes channel-specific faults via separate EN control and timing analysis of flag assertion sequence.
Is the exposed pad on AP2162SG-13 electrically connected to GND internally?
No - the exposed pad is thermally connected to the die substrate but is not electrically bonded to GND. It must be soldered to a PCB ground plane for thermal performance, yet must not serve as the primary current return path; dedicated Pin 1 (GND) remains the sole electrical ground connection.
