Product details
Overview
AP2156MPG-13 from Diodes Incorporated is a dual-channel, active-high enable, high-side USB power switch with 0.8A current limiting, 90mΩ RDS(ON) (MSOP-8EP), and integrated short-circuit/thermal protection. It delivers controlled 0.6ms rise time, 7ms FLG deglitch, and reverse current blocking for USB 2.0-compliant hot-swap ports in laptops and docking stations.
For engineers reviewing the AP2156MPG-13 datasheet, AP2156MPG-13 pinout, AP2156MPG-13 application, or AP2156MPG-13 equivalent, key selection criteria include active-high EN polarity, MSOP-8EP thermal performance (θJA = 60°C/W), dual independent FLG reporting, UVLO threshold (1.9V typ), and compliance with USB 2.0 power delivery requirements.
Technical Context
The AP2156 implements two independent high-side N-channel MOSFET drivers with dedicated current-sense FETs, enabling precise 0.8A over-current limiting without external resistors. Each channel features separate EN and open-drain FLG pins, supporting autonomous fault detection and recovery.
Its UVLO circuit disables both switches below 1.9V input, preventing erratic behavior during brown-out or hot-insertion. Thermal shutdown activates at +140°C with +25°C hysteresis, and the 7ms FLG blanking window suppresses false triggers from capacitive inrush transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 0.8A typical - maintains safe output current during overload without external components |
| RDS(ON) | 90mΩ max (MSOP-8EP, 5V, 25°C) - minimizes conduction loss and self-heating under 500mA continuous load |
| Rise Time | 0.6ms typical - enables soft-start to limit inrush current in USB and hot-plug applications |
| FLG Blanking | 7ms typical - prevents false over-current flags from capacitor charging transients |
| UVLO Threshold | 1.9V typical - ensures reliable turn-off during input undervoltage, critical for hot-swap integrity |
| Shutdown Current | 1µA max - supports ultra-low-power system standby states |
| Input Voltage Range | 2.7V–5.5V - covers full USB 2.0 VBUS tolerance and 3.3V/5V system rails |
Pinout & Package
AP2156MPG-13 is housed in an MSOP-8EP (Exposed Pad) package. The exposed pad must be externally connected to GND and thermal mass for optimal θJA = 60°C/W performance; it is not an electrical ground conduction path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1 / EN2 | Active-high enable inputs | Drive high (>2V) to activate respective channel; logic-compatible with 3.3V/5V microcontrollers |
| FLG1 / FLG2 | Open-drain fault report outputs | Pull low during over-current or over-temperature; require external pull-up for host interrupt signaling |
| OUT1 / OUT2 | High-side switched outputs | Deliver regulated power to downstream USB ports or peripherals; support reverse current blocking |
| IN | Main power input | Accepts 2.7V–5.5V supply; requires local 0.01–0.1µF ceramic bypass per Diodes' layout guidance |
| GND | Power and signal reference | Return path for load current and internal bias; connects to exposed pad for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable & flag | Enables per-port power control and isolated fault reporting in multi-port USB hubs |
| Integrated current-sense FET | Eliminates need for external sense resistors, preserving low RDS(ON) and PCB area |
| Reverse current blocking | Prevents backflow from powered downstream devices into the main supply during fault or disable |
| Thermal shutdown with hysteresis | +140°C trip with +25°C hysteresis enables auto-recovery after transient overload without host intervention |
| Green RoHS/lead-free packaging | Halogen- and antimony-free compound (<900ppm Br/Cl, <1000ppm Sb) meets IEC60950-1 CB and UL E322375 |
Applications
| USB 2.0 Dual-Port Hub | Laptop Docking Station |
|---|---|
|
Use Scenario: Two downstream USB ports on a self-powered hub requiring independent current limiting 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 |
|---|---|---|---|
| TUSB2036IPWR | Single-chip USB 2.0 hub controller with integrated 3-port power switches; no independent FLG per channel | Requires full hub functionality (transaction translation, enumeration); not a standalone power switch | Select when full USB hub IC capability is needed; not suitable for discrete power gating only |
| TPS2051BDBVR | Single-channel, active-high, 0.5A current limit, SO-6 package; no FLG deglitch or reverse blocking | Requires two units for dual-port use; lacks 7ms blanking and bidirectional fault immunity | Choose for cost-sensitive single-port designs where FLG reliability and reverse isolation are non-critical |
Compared with TUSB2036IPWR and TPS2051BDBVR, AP2156MPG-13 uniquely provides dual independent channels with per-port FLG reporting, 7ms deglitch, reverse current blocking, and MSOP-8EP thermal efficiency-making it optimal for discrete, high-reliability USB power gating where hub controller integration is unnecessary.

FAQ
What is the difference between AP2146 and AP2156?
AP2146 uses active-low enable inputs (EN1/EN2 pulled low to activate), while AP2156 uses active-high enable inputs (EN1/EN2 driven high to activate). Both share identical current limit (0.8A), RDS(ON), FLG behavior, and thermal specs. The part number suffix 'MPG-13' confirms this is the MSOP-8EP package variant of the AP2156.
Can AP2156MPG-13 drive a 1A load?
No. Its recommended maximum continuous load current is 0.5A per channel, though its current limit trips at 0.8A typical. Sustained 1A operation exceeds thermal limits-even in MSOP-8EP-and risks triggering thermal shutdown. For 1A applications, consider higher-rated switches like AP22653 or TPS2065D.
Is external pull-up required on FLG1 and FLG2?
Yes. FLG1 and FLG2 are open-drain outputs and require external pull-up resistors (typically 4.7kΩ to 5V or 3.3V) to generate a valid logic-high signal when no fault is present. Without pull-ups, FLG remains floating and cannot interface reliably with microcontroller interrupt pins.
Does AP2156MPG-13 support USB 3.0 power delivery?
No. AP2156MPG-13 is specified and qualified only for USB 2.0 applications. It does not meet USB 3.0's higher current (900mA), faster transient response, or BC1.2 charging protocol requirements. Use dedicated USB 3.x power switches such as TPS6598x or RT1718S for USB-C PD implementations.
