Product details
Overview
AP2152AMPG-13 from Diodes Incorporated is a dual-channel, active-high enable, current-limited high-side power switch optimized for USB 2.0 hub and hot-swap applications. It delivers 0.5A continuous per channel, features 85mΩ typical RDS(ON) at 5V, 2µs short-circuit response, integrated output discharge, and operates across 2.7V–5.5V input range.
For engineers reviewing the AP2152AMPG-13 datasheet, AP2152AMPG-13 pinout, AP2152AMPG-13 application, or AP2152AMPG-13 equivalent, this device supports precise current limiting (0.7A typ), UVLO (2.0V), thermal shutdown (140°C), and fault reporting with 7ms deglitch - critical for robust USB port protection and hot-plug system design.
Technical Context
The AP2152AMPG-13 integrates two independent P-channel MOSFET high-side switches with matched current-limit sensing, each featuring dedicated open-drain FLG outputs with internal 7ms blanking to suppress false over-current triggers during capacitive inrush. Its architecture combines fast short-circuit detection (2µs) with controlled soft-start (0.6ms rise time) and reverse current blocking.
It implements dual protection layers: per-channel current limiting (0.7A typ) with ganged mode capability (1.4A typ), plus thermal shutdown at 140°C with 25°C hysteresis. The discharge function activates automatically on disable, providing a 100Ω resistive path to safely bleed output capacitance without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit (typ) | 0.7A per channel - ensures safe operation under sustained overload without latch-off |
| RDS(ON) (typ) | 85mΩ at 5V - minimizes conduction loss and self-heating in compact MSOP-8EP package |
| Short-Circuit Response | 2µs - enables rapid current clamp before downstream damage occurs |
| Input Voltage Range | 2.7V–5.5V - fully covers USB 2.0 VBUS tolerance and industrial 3.3V/5V rails |
| UVLO Threshold | 2.0V (typ) - prevents erratic switching during brown-out or hot-insertion ramp-up |
| Thermal Shutdown | 140°C with 25°C hysteresis - provides self-resetting protection during extended faults |
| Discharge Resistance | 100Ω - actively discharges output caps when disabled, eliminating floating voltage hazards |
Pinout & Package
AP2152AMPG-13 is packaged in MSOP-8EP (exposed pad), offering enhanced thermal performance (θJA = 75°C/W) versus SO-8. The exposed pad must be soldered to PCB ground plane for optimal thermal dissipation and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power Input | Primary supply rail connection (2.7V–5.5V); feeds both channels |
| EN1 / EN2 | Active-High Enable Inputs | Independent digital control of each channel; logic high ≥2V enables respective switch |
| OUT1 / OUT2 | Switched Outputs | High-side switched VOUT nodes; support up to 0.5A continuous load each |
| FLG1 / FLG2 | Open-Drain Fault Flags | Active-low signals indicating over-current or over-temperature; include 7ms internal deglitch |
| GND | Ground Reference | Power and signal return; connects to exposed pad for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1/EN2 allow staggered or isolated channel activation - essential for USB port sequencing and power domain isolation |
| Integrated output discharge | 100Ω internal discharge path eliminates need for external bleeder resistors - reduces BOM count and board space |
| 7ms deglitched fault reporting | Prevents false FLG assertion during normal 4.7µF USB capacitor inrush - removes requirement for external RC filtering |
| Reverse current blocking | Prevents backfeed from loaded output to input rail - critical for multi-rail systems and battery backup integrity |
| Soft-start with 0.6ms rise time | Controls dV/dt to limit inrush current into heavy capacitive loads - avoids tripping upstream supplies or fuses |
Applications
| USB 2.0 Hub Port Protection | Laptop Docking Station Power Control |
|---|---|
Use Scenario: Protecting individual downstream ports on a 4-port USB 2.0 hub against short circuits and overloads. IC Role / Device Role / Timing Role: Dual-channel high-side switch providing per-port current limiting, fault flagging, and automatic discharge after disconnect. Use Value: Enables compliance with USB 2.0 specification requiring 120µF per port and over-current reporting - no external sense resistors or discharge FETs needed. |
Use Scenario: Managing power delivery to peripheral slots (HDMI, Ethernet, USB-C) in a laptop docking station. IC Role / Device Role / Timing Role: Independent channel control allows sequenced power-up/down of peripherals while monitoring each for faults. Use Value: Prevents system reset due to hot-plug inrush; 2µs fault response protects sensitive interface ICs from transient overcurrent events. |
| Set-Top Box USB Peripheral Ports | Industrial Thin Client Power Management |
Use Scenario: Providing protected 5V power to front-panel USB ports on cable/satellite set-top boxes. IC Role / Device Role / Timing Role: High-side switch with UVLO and thermal shutdown ensures reliable operation under variable ambient conditions and unregulated wall adapters. Use Value: 85mΩ RDS(ON) limits self-heating in confined enclosures; -40°C to +85°C rating supports deployment in living-room environments. |
Use Scenario: Controlling power to optional I/O modules (RS-485, CAN, GPIO expansion) in fanless industrial thin clients. IC Role / Device Role / Timing Role: Dual-channel switch enables modular power partitioning with independent fault reporting per module slot. Use Value: Integrated discharge prevents residual voltage on disconnected modules - satisfies safety requirements for field-replaceable units. |
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 |
|---|---|---|---|
| AP2142AMPG-13 | Identical specs except active-low enable inputs | Requires inverted logic control; unsuitable where host MCU lacks open-drain or level-shifting capability | Select only if system-level enable signaling is active-low and timing-critical sequencing demands matching polarity |
| TPS2051BDR | Single-channel, 0.5A, 100mΩ RDS(ON), no integrated discharge, 10ms fault blanking | Requires two devices and external discharge circuitry for dual-channel use; lacks reverse current blocking | Choose only for legacy designs already using TI's TPS20xx family and where discharge is handled externally |
Compared with AP2142AMPG-13, the AP2152AMPG-13 simplifies MCU interface by eliminating level translation; versus TPS2051BDR, it reduces component count and improves system-level reliability through integrated discharge and reverse-blocking - directly lowering BOM cost and layout complexity.

FAQ
What is the maximum continuous output current per channel for AP2152AMPG-13?
The AP2152AMPG-13 supports 0.5A continuous output current per channel under recommended operating conditions (TA ≤ +85°C, VIN = 5.0V). This is derated from the 0.7A typical current-limit threshold to ensure long-term reliability and thermal stability in the MSOP-8EP package.
Does AP2152AMPG-13 require external components for output discharge?
No. The AP2152AMPG-13 integrates an internal 100Ω discharge path that activates automatically when EN1 or EN2 is de-asserted. This eliminates the need for external resistors or FETs, reducing BOM count and PCB area while ensuring safe discharge of output capacitance during hot removal.
How does the 7ms deglitch on the FLG pin improve system reliability?
The 7ms deglitch prevents false fault reporting during normal high-capacitance load turn-on (e.g., 4.7µF USB port caps), which can cause momentary inrush currents exceeding 1A. By ignoring transients shorter than ~7ms, the device avoids unnecessary system interrupts or port disablement - no external RC filter required.
Can AP2152AMPG-13 be used in automotive applications?
The AP2152AMPG-13 is specified for -40°C to +85°C ambient operation and meets UL/IEC safety certifications, but it is not AEC-Q200 qualified. It is suitable for industrial and consumer applications including set-top boxes and docking stations, but not for under-hood automotive environments requiring extended temperature or qualification testing.
