Product details
Overview
AP2162AMPG-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-compliant hot-swap and capacitive-load power distribution. It delivers 85mΩ typical RDS(ON) at 5V input, 2µs short-circuit response, and built-in UVLO (2.0V threshold), thermal shutdown (+140°C), and 7ms deglitched fault flag reporting - deployed in LCD monitors and docking stations.
For engineers reviewing the AP2162AMPG-13 datasheet, AP2162AMPG-13 pinout, AP2162AMPG-13 application, or AP2162AMPG-13 equivalent, key selection criteria include active-low EN polarity, dual independent channel control, output discharge resistance (~100Ω), SO-8EP package thermal performance (θJA = 75°C/W), and compliance with USB 2.0 hub power sequencing requirements.
Technical Context
The AP2162A implements two independent pMOS high-side switches with per-channel current sensing, thermal monitoring, and open-drain FLG outputs. Each channel features dedicated EN inputs and FLG pins, enabling asynchronous control and fault isolation. The internal discharge path activates only when EN is deasserted or during UVLO, providing controlled VOUT capacitor discharge without external components.
Its protection architecture combines fast overcurrent limiting (1.4A typ, 2µs response), thermal shutdown with +25°C hysteresis, and 7ms deglitch on FLG to suppress false triggers from inrush transients. The device operates across 2.7V–5.5V input and supports load currents up to 1.0A continuous per channel under -40°C to +85°C ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 1.4A typical per channel - clamps output current to prevent damage during overload or short-circuit events. |
| RDS(ON) | 85mΩ typical (U-DFN3030-8) at 5V/25°C - minimizes conduction loss and self-heating under 1A load. |
| Short-Circuit Response | 2µs - enables rapid current limiting before energy dissipation exceeds safe junction temperature limits. |
| Output Discharge Resistance | 100Ω typical - provides controlled discharge of output capacitance when disabled, eliminating floating voltage hazards. |
| UVLO Threshold | 2.0V typical - ensures switch remains off until input rail stabilizes, preventing erratic turn-on during power ramp-up. |
| FLG Blanking Time | 7ms typical - filters transient overcurrent spikes (e.g., from large CL charging), avoiding false fault reporting. |
| Thermal Shutdown | +140°C activation with +25°C hysteresis - cycles switch off/on to limit average power dissipation during sustained faults. |
Pinout & Package
AP2162AMPG-13 is supplied in an MSOP-8EP (exposed pad) package, optimized for thermal performance (θJA = 75°C/W) in space-constrained USB power delivery applications. The exposed pad must be soldered to PCB ground plane for effective heat dissipation and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power Input | Primary supply rail connection (2.7V–5.5V); feeds both channels and internal bias circuitry. |
| EN1 / EN2 | Active-Low Enable Inputs | Independent digital control lines; low state enables corresponding channel; internal pull-down ensures default-off safety. |
| OUT1 / OUT2 | Switched Power Outputs | High-side switched outputs delivering regulated current-limited power to downstream loads (e.g., USB ports). |
| FLG1 / FLG2 | Open-Drain Fault Flags | Active-low indicators signaling overcurrent or overtemperature on respective channel; 7ms deglitch prevents false asserts. |
| GND | Ground Reference | Common return path for power, logic, and thermal pad; must be low-impedance for stable operation and thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent channel control | Enables selective power sequencing for multi-port USB hubs or mixed-voltage subsystems without cross-talk. |
| Integrated output discharge | Eliminates need for external bleed resistors; discharges output caps safely during disable/power-down to meet USB hot-unplug specs. |
| 2µs short-circuit response | Prevents destructive energy buildup during hard shorts, supporting robust hot-swap reliability in industrial docking systems. |
| 7ms FLG deglitch | Rejects inrush-induced false faults from 10µF+ output capacitors, removing requirement for external RC filtering on flag lines. |
| Thermal cycling protection | Shuts down at +140°C and re-enables only after cooling by +25°C, allowing safe intermittent operation under sustained overload. |
Applications
| USB 2.0 Hub Power Management | LCD Monitor Port Protection |
|---|---|
|

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 |
|---|---|---|---|
| TPL9202DQNR | Active-high EN, 1.5A limit, 65mΩ RDS(ON), no integrated discharge | Requires external discharge resistor; better suited for always-on USB host controllers needing higher efficiency | Select if active-high logic interface and lower conduction loss outweigh need for integrated discharge. |
| TPS2052BDR | Single-channel, 1.5A, no FLG deglitch, 100mΩ RDS(ON), no discharge | Needs two devices for dual-channel use; lacks 7ms blanking, increasing false fault risk with large CL | Choose only for cost-sensitive single-load applications where FLG reliability is secondary. |
Compared with TPL9202DQNR and TPS2052BDR, AP2162AMPG-13 uniquely combines active-low EN, integrated discharge, and 7ms FLG deglitch in a thermally efficient MSOP-8EP package - making it optimal for space-constrained, safety-critical USB hot-swap designs requiring zero external protection components.

FAQ
What is the maximum continuous load current per channel for AP2162AMPG-13?
The maximum continuous load current per channel is 1.0A, as specified in the Recommended Operating Conditions table. This rating accounts for thermal derating across the full -40°C to +85°C ambient range and ensures reliable operation without exceeding the +140°C thermal shutdown threshold under worst-case RDS(ON) and layout conditions.
Does AP2162AMPG-13 require external components for output discharge?
No. AP2162AMPG-13 integrates an internal nMOS discharge switch with ~100Ω on-resistance that activates automatically when EN is deasserted or during UVLO. This eliminates the need for external bleed resistors while ensuring controlled discharge of output capacitance to meet USB hot-unplug safety requirements.
How does the 7ms FLG deglitch function improve system reliability?
The 7ms deglitch window on each FLG pin suppresses transient overcurrent pulses caused by capacitor inrush or noise spikes, preventing false fault assertions. This allows the device to tolerate brief current surges (e.g., from 10µF output caps charging) without triggering host-controller interrupts or unnecessary system resets.
Can AP2162AMPG-13 be used in automotive applications?
AP2162AMPG-13 is not AEC-Q100 qualified and is rated for -40°C to +85°C ambient operation. While it meets industrial temperature requirements, Diodes Incorporated explicitly states that automotive-grade versions require separate qualification, PPAP capability, and IATF 16949 manufacturing - none of which apply to this part number.
