Product details
Overview
AP2162ASG-13 from Diodes Incorporated is a dual-channel, active-low enable, 1.4A current-limiting high-side power switch with integrated output discharge, designed for USB and hot-swap applications. It features 85mΩ typical RDS(ON), 2µs short-circuit response time, 0.6ms typical output rise time, and operates across 2.7V–5.5V input voltage range. Used in laptop USB hubs to prevent inrush damage during peripheral insertion.
For engineers reviewing the AP2162ASG-13 datasheet, AP2162ASG-13 pinout, AP2162ASG-13 application, or AP2162ASG-13 equivalent, key selection criteria include enable polarity (active-low), per-channel current limit accuracy (±20% over temperature), thermal shutdown threshold (+140°C), and SO-8 package compatibility with PCB layout constraints for USB port power management.
Technical Context
The AP2162ASG-13 implements two independent pMOS high-side switches with dedicated EN1/EN2 inputs and open-drain FLG1/FLG2 fault outputs. Each channel integrates current sensing via sense-FET architecture-eliminating external shunt resistors-and employs deglitched (7ms typ) flag reporting to suppress false triggers from capacitive load transients.
Its discharge function activates automatically upon disable or UVLO (<2.0V), providing a 100Ω internal resistive path to safely dissipate output capacitance energy. The device combines undervoltage lockout, reverse current blocking, and thermal hysteresis (+25°C) to ensure robust operation under heavy capacitive loads and short-circuit conditions without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit (Typ) | 1.4A per channel - clamps output current at safe level during overload, preventing damage to downstream circuitry |
| RDS(ON) (Typ) | 85mΩ at 5V - minimizes conduction loss and self-heating under 1A continuous load |
| Short-Circuit Response | 2µs - enables rapid current limiting before destructive energy accumulates in output capacitor |
| Output Rise Time | 0.6ms typical - controls inrush current during hot-plug events, reducing stress on host supply |
| Input Voltage Range | 2.7V to 5.5V - supports full USB 2.0/3.0 VBUS tolerance and legacy 3.3V system rails |
| Thermal Shutdown | +140°C with +25°C hysteresis - cycles power switch off/on until fault clears, avoiding permanent latch-up |
| Discharge Resistance | 100Ω - provides controlled, non-oscillatory discharge of up to 10µF output capacitance when disabled |
Pinout & Package
AP2162ASG-13 is supplied in SO-8 package (lead-free, RoHS-compliant, exposed pad not electrically connected). Pin 1 = FLG1, Pin 2 = OUT1, Pin 3 = FLG2, Pin 4 = OUT2, Pin 5 = GND, Pin 6 = EN2, Pin 7 = EN1, Pin 8 = IN. Exposed pad must be soldered to GND plane for thermal performance but not used as primary current return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 8) | Main power input | Accepts 2.7–5.5V supply; feeds both channels; requires local 0.1–1µF ceramic bypass |
| EN1 / EN2 (Pins 7 / 6) | Active-low enable inputs | Logic low enables respective channel; internal pull-down ensures default-off state on power-up |
| OUT1 / OUT2 (Pins 2 / 4) | Switched power outputs | Deliver regulated current-limited power to USB ports or peripheral rails; support reverse current blocking |
| FLG1 / FLG2 (Pins 1 / 3) | Open-drain fault flags | Assert low after 7ms deglitch on overcurrent or overtemperature; require external pull-up for MCU monitoring |
| GND (Pin 5) | Power and signal reference | Common return for input, output, and logic; must be low-impedance connection to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel current limiting | Independent 1.4A per channel with ganged mode up to 2.8A - enables flexible power partitioning for multi-port USB hubs |
| Integrated output discharge | 100Ω internal discharge path activated on disable - eliminates need for external bleed resistors in space-constrained designs |
| 7ms deglitched fault reporting | No external RC filtering required - prevents false FLG assertion from transient inrush during hot-plug or large CL charging |
| Reverse current blocking | Prevents backflow from loaded output to input rail - critical for shared VBUS architectures and battery-backed systems |
| UVLO with 2.0V threshold | Ensures switch remains off until stable input is established - avoids erratic behavior during brown-out or hot-insertion |
Applications
| USB 2.0 Hub Power Management | Laptop Docking Station Port Control |
|---|---|
|
Use Scenario: Managing power delivery to four downstream USB 2.0 ports on a compact hub board with 10µF total output capacitance. IC Role / Device Role / Timing Role: Dual high-side switch controlling VBUS per port, enforcing current limits and enabling/disabling ports individually via EN1/EN2. Use Value: Prevents host controller reset due to inrush; 2µs fault response protects hub ICs; discharge function clears residual VBUS before port re-enumeration. |
Use Scenario: Isolating USB-C alternate mode peripherals (e.g., DisplayPort, Ethernet) in a multi-function docking station with shared 5V rail. IC Role / Device Role / Timing Role: Per-peripheral power gate with independent fault reporting (FLG1/FLG2) to host MCU for diagnostics and graceful shutdown. Use Value: Enables hot-plug detection and port-level power cycling without affecting other dock functions; reverse blocking prevents backfeed into inactive lanes. |
| Set-Top Box USB Peripheral Interface | Industrial USB Host Controller Protection |
|
Use Scenario: Providing protected 5V power to front-panel USB ports on an IPTV set-top box with ESD-sensitive tuner modules nearby. IC Role / Device Role / Timing Role: High-side switch with 2kV HBM ESD rating placed between main 5V rail and USB receptacles to absorb transients. Use Value: Eliminates need for discrete TVS diodes per port; UVLO ensures clean power-up sequencing; thermal shutdown prevents latch-up during cable short events. |
Use Scenario: Safeguarding embedded USB host controllers in factory automation HMIs where field technicians frequently connect/disconnect test tools. IC Role / Device Role / Timing Role: Dual-channel power gate placed upstream of USB PHY to isolate faults before they propagate to controller or system bus. Use Value: FLG outputs feed directly to watchdog timer; 0.6ms rise time prevents bus reset from inrush; SO-8 package allows standard wave-solder reflow. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB2036IPW | Single-channel, 1.5A limit, no integrated discharge, 3.3V-only operation | Lacks dual independent control and output discharge; requires external discharge circuitry | Only suitable if single-channel operation and 3.3V rail are acceptable; not drop-in compatible |
| TPS2051BDR | Single-channel, 1.5A limit, active-high enable, 120mΩ RDS(ON), no UVLO | Higher conduction loss; no undervoltage lockout; requires external UVLO circuit for hot-swap safety | Acceptable for low-cost 5V-only applications where thermal margin is sufficient and UVLO is managed externally |
Compared with TUSB2036IPW and TPS2051BDR, AP2162ASG-13 delivers true dual independent control, integrated discharge, lower RDS(ON), and guaranteed UVLO-making it uniquely suited for compact, multi-port USB hot-swap designs requiring minimal BOM count and robust fault handling.

FAQ
What is the enable polarity of AP2162ASG-13?
The AP2162ASG-13 uses active-low enable logic: EN1 and EN2 must be pulled low to turn on their respective channels. Internal pull-down resistors ensure default-off behavior at power-up, eliminating need for external biasing in most USB applications.
Does AP2162ASG-13 support ganged operation of both channels?
Yes-when OUT1 and OUT2 are tied together, the device supports ganged current limiting up to 2.8A typical (ILIMIT_G), with coordinated thermal shutdown and fault reporting. This configuration is validated in the datasheet for high-current single-rail applications like monitor USB hubs.
Can AP2162ASG-13 drive a 10µF output capacitor without instability?
Yes-the device is characterized with 10µF output capacitance and includes built-in soft-start (0.6ms rise time) and discharge control. Its current-limit architecture and 2µs fault response prevent oscillation or latch-up, even with full USB 2.0 hub capacitance requirements.
Is the exposed pad on the SO-8 package electrically connected?
No-the exposed pad on AP2162ASG-13's SO-8 package is a thermal pad only. It must be soldered to a GND copper pour for heat dissipation but is not electrically connected to any internal node and should not serve as a current return path.
