Product details
Overview
AP2196SG-13 from Diodes Incorporated is a dual-channel, active-high enable, high-side USB power switch with integrated current limiting, thermal protection, and reverse current blocking. It delivers 1.5A continuous load per channel, features 90mΩ typical RDS(ON) (MSOP-8EP) / 100mΩ (SO-8), operates from 2.7V–5.5V input, and provides 7ms deglitched fault reporting via open-drain FLG pins - deployed in USB 2.0 host/hub and hot-swap power distribution systems.
For engineers reviewing the AP2196SG-13 datasheet, AP2196SG-13 pinout, AP2196SG-13 application, or AP2196SG-13 equivalent, key selection criteria include active-high EN logic polarity, dual independent enable/fault signaling, 2.1A current-limit accuracy, UVLO threshold at 1.9V (typ), and SO-8 package compatibility with standard USB port layout constraints.
Technical Context
The AP2196SG-13 integrates two independent high-side N-channel MOSFET power switches with matched current-limit circuitry (2.1A typ), internal thermal shutdown (140°C trip, 25°C hysteresis), and under-voltage lockout (1.9V typ). Each channel features dedicated EN and FLG pins, enabling discrete control and fault isolation in multi-port USB systems.
Its architecture employs sense-FET current monitoring (no external resistor), reverse-blocking capability during disable, and controlled 0.6ms typical output rise time to limit inrush. The 7ms FLG deglitch window suppresses transient over-current events caused by capacitive loads - eliminating need for external RC filtering in compliant USB 2.0 designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V–5.5V: Supports full USB 2.0 bus voltage tolerance and accommodates brown-out conditions down to 2.7V without false turn-off. |
| Continuous Load Current | 1.5A per channel: Maximum sustained output current before thermal limiting engages under worst-case ambient and PCB layout conditions. |
| RDS(ON) (SO-8) | 100mΩ (typ): Enables ≤150mW conduction loss at 1.5A, reducing thermal stress in compact SO-8 footprint. |
| Current Limit Accuracy | 2.1A (typ): Tight ±15% tolerance ensures reliable short-circuit response across temperature and process variation. |
| FLG Blanking Time | 7ms (typ): Suppresses false fault assertions during capacitor charging transients, enabling direct connection to microcontroller GPIO without debouncing. |
| Shutdown Current | 1µA (max): Minimizes standby power draw in battery-backed or always-on USB peripheral applications. |
| UVLO Threshold | 1.9V (typ): Prevents erratic switching during power-up/down sequences, ensuring clean enable/disable behavior in hot-plug scenarios. |
Pinout & Package
AP2196SG-13 is supplied in an SO-8 package with exposed pad (Green, RoHS-compliant, lead-free). The exposed pad must be externally connected to GND and thermal mass for optimal thermal performance (θJA = 110°C/W); it is not intended as primary electrical ground path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1 / EN2 | Active-high enable inputs | Direct TTL/CMOS-compatible logic control of each channel; no pull-up required - simplifies interface with USB controller GPIOs. |
| FLG1 / FLG2 | Open-drain fault indicators | Assert low on over-current or over-temperature; 7ms deglitch eliminates need for external RC filters in USB hub BOM. |
| OUT1 / OUT2 | Switched output terminals | High-side outputs capable of reverse current blocking when disabled - prevents backfeed between USB ports. |
| IN | Main power input | Accepts 2.7V–5.5V supply; requires local 0.1µF ceramic bypass to GND per datasheet layout guidelines. |
| GND | Power and signal reference | Common return for internal circuitry and external decoupling; connects to exposed pad for thermal management. |
| OUT1 / OUT2 (Pin 8 / Pin 5) | Output voltage pins | Pin 8 (OUT1) and Pin 5 (OUT2) deliver switched VBUS to downstream USB ports; routed separately to avoid cross-talk. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable/fault signaling | EN1/EN2 and FLG1/FLG2 allow per-port control and diagnostics in 2-port USB hubs without multiplexing overhead. |
| Reverse current blocking | Prevents backflow from powered downstream devices into upstream VBUS rail - critical for USB OTG and self-powered hub compliance. |
| Controlled 0.6ms rise time | Soft-start limits inrush current to <3A peak during hot-plug, meeting USB 2.0 specification for port power sequencing. |
| Integrated 7ms FLG deglitch | Eliminates false over-current flags from 68µF output capacitance charging transients - removes need for external timing components. |
| Thermal shutdown with 25°C hysteresis | Auto-recovery cycling enables fault-tolerant operation during temporary overload, avoiding permanent latch-off in transient conditions. |
Applications
| USB 2.0 Host Hub | Hot-Swap Peripheral Module |
|---|---|
Use Scenario: Dual-port desktop USB hub supplying power to keyboards, mice, and flash drives from a single upstream host connection. IC Role / Device Role / Timing Role: High-side power switch managing VBUS delivery per port with independent enable and fault reporting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel USB power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2186SG-13 | Identical specs except active-low EN logic polarity; shares same SO-8 package, RDS(ON), and FLG timing. | Requires inverted enable signal from host controller; unsuitable where GPIO drive strength or logic level translation is constrained. | Select only if system design mandates active-low control; otherwise AP2196SG-13 avoids level-shifting complexity. |
| TUSB2036IPWR | Integrated USB 2.0 hub controller + power switches; includes built-in transceivers, PLL, and configuration EEPROM - not a standalone switch. | Replaces both USB PHY and power switching functions; adds USB enumeration, suspend/resume, and port power management logic. | Choose only when full hub functionality is needed; AP2196SG-13 is preferred for discrete power gating in custom hub or non-USB hot-swap applications. |
Compared with AP2186SG-13, AP2196SG-13 eliminates external inverters in active-high control systems; versus TUSB2036IPWR, it offers lower BOM cost and higher flexibility in non-standard USB implementations where only power switching - not protocol handling - is required.

FAQ
What is the maximum continuous current per channel for AP2196SG-13?
The AP2196SG-13 supports 1.5A continuous load current per channel under recommended operating conditions (TA ≤ +85°C, SO-8 package, proper PCB thermal layout). This rating accounts for internal power dissipation and thermal shutdown margin - exceeding 1.5A risks triggering thermal limiting even with nominal current-limit threshold of 2.1A.
Does AP2196SG-13 require external components for over-current fault filtering?
No. The AP2196SG-13 integrates a 7ms deglitch circuit on both FLG1 and FLG2 outputs, which suppresses false over-current assertions caused by output capacitor charging transients. This eliminates the need for external RC filters or debounce circuitry typically required with discrete fault-reporting switches.
Can AP2196SG-13 be used in USB 3.0 applications?
The AP2196SG-13 is specified and qualified for USB 2.0 compliance only. While its electrical characteristics (e.g., RDS(ON), rise time) may function in USB 3.0 power paths, it lacks USB 3.0-specific requirements such as SuperSpeed signal integrity support, higher current ratings (up to 900mA per port), and associated certification testing - use only in USB 2.0 or generic hot-swap power gating roles.
How does the reverse current blocking feature operate?
When disabled (EN = low), the internal MOSFET body diode is reverse-biased due to integrated charge-pump and gate-control circuitry, preventing current flow from OUT to IN. This blocks backfeed from powered downstream devices - essential for USB OTG, self-powered hubs, and systems with multiple power domains sharing a common VBUS rail.
