Product details
Overview
AP2152ASG-13 from Diodes Incorporated is a dual-channel, 0.5A current-limited high-side power switch with active-high enable, integrated output discharge, 85mΩ RDS(ON), 2µs short-circuit response, and built-in UVLO (2.0V typ), thermal shutdown (140°C), and 7ms deglitched fault flag - designed for USB 2.0 hub port power control in laptops and docking stations.
For engineers reviewing the AP2152ASG-13 datasheet, AP2152ASG-13 pinout, AP2152ASG-13 application, or AP2152ASG-13 equivalent, key selection criteria include per-channel 0.7A current limit accuracy, SO-8 package thermal resistance (115°C/W), reverse current blocking, controlled 0.6ms rise time, and compatibility with heavy capacitive loads up to 120µF per USB 2.0 spec.
Technical Context
The AP2152ASG-13 implements two independent P-MOS high-side switches with current-sense FETs for accurate 0.7A per-channel over-current detection and clamping. Each channel features dedicated open-drain FLG outputs with 7ms deglitching to suppress false reporting during inrush transients.
Its functional block includes UVLO (2.0V threshold), thermal sensing with 25°C hysteresis, soft-start via internal slew-rate control (0.6ms typical TR), and N-MOS-based discharge circuitry activated only when EN is de-asserted - ensuring safe, controlled VOUT capacitor discharge without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit (typ) | 0.7A per channel - sets precise trip threshold before current limiting engages |
| RDS(ON) (typ) | 85mΩ at 5V/25°C (SO-8) - minimizes conduction loss and self-heating under 500mA load |
| Short-Circuit Response | 2µs - enables rapid current clamp to protect downstream circuitry during hard shorts |
| Output Rise Time | 0.6ms typical - ensures controlled voltage ramp to limit inrush into 120µF USB loads |
| UVLO Threshold | 2.0V typical - prevents switch turn-on until input rail stabilizes, critical for hot-plug safety |
| Thermal Shutdown | 140°C with 25°C hysteresis - cycles switch off/on to sustain operation under sustained overload |
| Discharge Resistance | 100Ω - provides defined RC decay path for residual VOUT when disabled |
Pinout & Package
AP2152ASG-13 is supplied in SO-8 package (JEDEC MS-012AC), with exposed pad thermally connected to GND. Pin functions are validated per Diodes DS32191 Rev. 3–2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power ground reference | Primary return path for both channels and thermal pad anchor point |
| IN (Pin 2) | Main power input | Accepts 2.7–5.5V supply; feeds both high-side switches |
| EN1 (Pin 3) | Channel 1 enable input | Active-high logic; controls OUT1 independently |
| EN2 (Pin 4) | Channel 2 enable input | Active-high logic; controls OUT2 independently |
| FLG2 (Pin 5) | Channel 2 fault indicator | Open-drain, active-low signal asserting after 7ms deglitch on OC/OT |
| OUT2 (Pin 6) | Channel 2 switched output | Drives load; supports reverse current blocking when disabled |
| OUT1 (Pin 7) | Channel 1 switched output | Drives load; supports reverse current blocking when disabled |
| FLG1 (Pin 8) | Channel 1 fault indicator | Open-drain, active-low signal asserting after 7ms deglitch on OC/OT |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1/EN2 allow asynchronous control of each 0.5A channel for flexible power sequencing |
| Integrated output discharge | 100Ω internal discharge path eliminates need for external bleed resistors on USB ports |
| Reverse current blocking | Prevents backflow from VOUT to VIN when disabled - essential for multi-rail systems |
| 7ms deglitched FLG output | Rejects transient inrush spikes without external RC filtering, simplifying host MCU interrupt handling |
| USB-compliant timing | 0.6ms rise time meets USB 2.0 hub VCONN ramp requirements for 120µF load |

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 |
|---|---|---|---|
| AP2142ASG-13 | Identical specs except active-low EN1/EN2 logic | Requires inverted enable signals from host MCU; no change to protection or timing behavior | Select when system-level logic uses active-low control lines and avoids level-shifting. |
| TPS2052BDR | 0.5A per channel, 110mΩ RDS(ON), no integrated discharge, 12ms FLG blanking | Lacks output discharge function; requires external resistor for VOUT bleed; higher conduction loss | Choose only if discharge is handled externally and thermal budget allows higher RDS(ON). |
Compared with AP2142ASG-13, AP2152ASG-13 offers direct MCU GPIO compatibility without inversion; versus TPS2052BDR, it delivers lower conduction loss, integrated discharge, and faster fault response - directly reducing component count and improving USB port reliability.

FAQ
What is the maximum continuous load current per channel for AP2152ASG-13?
The AP2152ASG-13 supports 0.5A maximum continuous load current per channel under recommended operating conditions (TA = –40°C to +85°C, VIN = 2.7–5.5V). Its 0.7A typical current limit provides headroom for transient inrush while maintaining safe thermal operation in SO-8 package.
Does AP2152ASG-13 require external components for output discharge?
No. AP2152ASG-13 integrates an N-MOS discharge switch with 100Ω on-resistance, activated automatically when EN1 or EN2 is de-asserted. This eliminates the need for external bleed resistors, saving PCB space and cost while ensuring consistent discharge behavior across temperature.
How does the 7ms FLG deglitch timeout improve system reliability?
The 7ms deglitch window prevents false fault assertions caused by capacitive inrush currents during normal power-up or hot-plug events. By ignoring transients shorter than 4–15ms (typ/max), the FLG pin delivers only sustained over-current or over-temperature events to the host MCU - reducing firmware interrupt overhead and false shutdowns.
Can AP2152ASG-13 be used in USB 3.0 applications?
AP2152ASG-13 is specified and qualified for USB 2.0 applications (120µF max load per port). While its electrical specs may function in some USB 3.0 implementations, Diodes does not guarantee compliance with USB 3.0's stricter 10µs inrush timing or 10µF load requirements - use only after full system validation.
