Product details
Overview
AP1212HSL-13 from Diodes Incorporated is a dual-channel high-side USB power switch IC with independent enable and fault flag control, designed for bus-powered and self-powered USB hubs and peripheral ports. It delivers 500mA continuous current per channel, features 110mΩ typical RDS(ON), 1.25A short-circuit current limit, and 1ms soft-start turn-on to suppress inrush-induced voltage droop.
For engineers reviewing the AP1212HSL-13 datasheet, AP1212HSL-13 pinout, AP1212HSL-13 application, or AP1212HSL-13 equivalent, key selection criteria include USB-compliant current limiting, independent open-drain fault flags per channel, thermal shutdown with 10°C hysteresis, UVLO at 2.4V, and SOP-8L package compatibility with 3.3V/5V logic enables.
Technical Context
The AP1212HSL-13 integrates two N-channel MOSFET high-side switches with internal charge pumps, enabling operation from 2.7V–5.5V input while maintaining low on-resistance. Each channel includes independent current-limit sensing, thermal shutdown detection, and under-voltage lockout circuitry.
Its fault flag outputs (FLG1/FLG2) are open-drain and active-low, asserting during overcurrent, UVLO, or thermal events. Enable inputs (EN1/EN2) support both active-high (H suffix) and active-low (L suffix) logic, with 1μA off-state supply current and 110μA on-state current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports both 3.3V and 5V USB system rails without external level shifting. |
| Continuous Current per Channel | 500mA minimum - meets USB 2.0 downstream port current requirement for bus-powered devices. |
| RDS(ON) (Typ.) | 110mΩ at VIN = 5V - ensures ≤250mV voltage drop at 500mA, satisfying USB voltage-drop compliance. |
| Short-Circuit Current Limit | 1.25A maximum - provides robust fault protection while staying below UL 25VA safety threshold. |
| Turn-On Rise Time | 1ms typical - soft-start prevents upstream voltage sag during hot-plug insertion of USB peripherals. |
| Fault Flag Output Type | Open-drain, active-low - allows wired-OR connection to microcontroller interrupt lines with pull-up flexibility. |
| UVLO Threshold | 2.4V typical rising - holds switches disabled until stable USB VBUS is established, preventing erratic behavior. |
Pinout & Package
SOP-8L (Small Outline Package, 8-lead, lead-free, green molding compound), 1.27mm pitch, 4.9mm × 6.0mm body size, θJA = 165°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN1) | Channel 1 Enable Input | Active-high logic input (H suffix); must be driven - floating not allowed; compatible with 3.3V/5V CMOS levels. |
| 2 (FLG1) | Channel 1 Fault Flag Output | Open-drain output pulled low during overcurrent, UVLO, or thermal shutdown; requires external pull-up. |
| 3 (EN2) | Channel 2 Enable Input | Independent active-high enable for second USB port; decouples control between downstream devices. |
| 4 (FLG2) | Channel 2 Fault Flag Output | Dedicated fault indicator per port - enables per-port USB controller diagnostics without shared signaling. |
| 5 (GND) | Power and Signal Ground | Common return for internal circuitry, MOSFET sources, and logic; requires low-impedance PCB plane connection. |
| 6 (OUT2) | Channel 2 Switch Output | Source terminal of second N-MOSFET; connects directly to downstream USB VBUS line after ferrite bead filtering. |
| 7 (OUT1) | Channel 1 Switch Output | Source terminal of first N-MOSFET; electrically isolated from OUT2 to prevent cross-port fault propagation. |
| 8 (IN) | Supply Input | Drain terminal of both MOSFETs and internal bias rail; connects to upstream USB VBUS before local bulk capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side switching | Enables per-port power control and fault isolation in multi-port USB hubs without shared enable/fault lines. |
| 1ms soft-start with current limiting | Prevents >100mA inrush surges into downstream device capacitance, eliminating upstream port reset during hot-plug. |
| Thermal shutdown with 10°C hysteresis | Disables both channels at 140°C and re-enables only after die cools to ≤130°C - avoids thermal oscillation under sustained overload. |
| Independent open-drain fault flags | Allows direct connection to MCU GPIO pins with shared pull-up; supports simultaneous fault reporting without bus contention. |
| 3.3V/5V logic-compatible enable inputs | Accepts standard USB host controller I/O voltages without level translators - simplifies interface design in mixed-voltage systems. |
Applications
| USB Hub Power Management | Bus-Powered Peripheral Port |
|---|---|
|

IC Role / Device Role / Timing Role: Robust high-side switch with ESD-hardened I/O (500V HBM), thermal shutdown, and fast fault flag response. Use Value: Withstands repeated hot-plug cycles and transient overloads; FLG assertion triggers immediate firmware logging and port disable for traceability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel USB high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2146WU-7 | Single-channel, 2.7–5.5V, 1.5A current limit, integrated 100Ω load switch resistor, WLCSP-6 package. | Requires two units for dual-port use; lacks independent fault flags; smaller footprint but no SOP-8L drop-in replacement. | Select when board space is constrained and per-port fault reporting is not required. |
| AP2156WM-7 | Dual-channel, 2.7–5.5V, 1.5A current limit, 80mΩ RDS(ON), WLCSP-12 package, no UVLO hysteresis spec. | Lower on-resistance improves efficiency but uses non-pin-compatible WLCSP; missing explicit UVLO hysteresis data in datasheet. | Select for higher-current USB PD sink applications where thermal performance outweighs legacy SOP-8L compatibility. |
Compared with AP1212HSL-13, AP2146WU-7 offers higher current limit but sacrifices dual-channel integration and fault flag independence, while AP2156WM-7 improves conduction loss and packaging density but removes SOP-8L mechanical compatibility and documented UVLO hysteresis - making AP1212HSL-13 optimal for legacy USB 2.0 hub redesigns requiring minimal layout change.

FAQ
What does the "HSL" suffix indicate in AP1212HSL-13?
The "H" denotes active-high enable logic (EN1/EN2 asserted high), "S" specifies SOP-8L package, "L" confirms lead-free finish, and "-13" indicates 13-inch tape-and-reel packaging with 2500 units per reel. This suffix fully defines the logic polarity, package, environmental compliance, and shipping format.
Can AP1212HSL-13 be used in USB 3.0 applications?
No - AP1212HSL-13 is specified and characterized only for USB 2.0 compliance (500mA per port, 2.7–5.5V operation). USB 3.0 requires 900mA per port and stricter EMI/switching noise control; Diodes recommends AP22601 or AP22802 for USB 3.x power switching.
Is an input bypass capacitor mandatory for AP1212HSL-13?
Yes - a 0.1µF ceramic capacitor placed between IN and GND, located within 3mm of the device, is mandatory. Without it, output short-circuit transients can induce ringing on the IN rail exceeding 7V absolute maximum rating, risking permanent damage to internal control circuitry.
Why does the datasheet state "NOT RECOMMENDED FOR NEW DESIGN"?
Diodes has superseded AP1212HSL-13 with AP2146 and AP2156, which offer lower RDS(ON), improved thermal metrics, and enhanced ESD robustness. However, AP1212HSL-13 remains fully qualified, in active production, and supported for existing designs requiring SOP-8L footprint and identical functionality.
