Product details
Overview
AP2146MPG-13 from Diodes Incorporated is a dual-channel, active-low high-side USB power switch with 0.8A current limiting, 90mΩ typical RDS(ON) (MSOP-8EP), and integrated short-circuit/thermal protection. It operates from 2.7V–5.5V input, delivers controlled 0.6ms rise time, and supports hot-swap in USB 2.0-compliant host/hub ports.
For engineers reviewing the AP2146MPG-13 datasheet, AP2146MPG-13 pinout, AP2146MPG-13 application, or AP2146MPG-13 equivalent, key selection criteria include enable polarity (active-low), dual independent fault reporting (FLG1/FLG2), reverse current blocking, 7ms deglitch on flag outputs, and thermal shutdown at +140°C with +25°C hysteresis.
Technical Context
The AP2146MPG-13 integrates two independent high-side N-channel MOSFETs with current-sense FETs for accurate 0.8A over-current detection and UVLO threshold of 1.9V (typ). Each channel features separate EN and FLG pins, enabling independent control and fault isolation in multi-port systems.
Its internal thermal shutdown circuit activates at +140°C junction temperature and holds off until die cools by +25°C hysteresis; the 7ms FLG deglitch window suppresses false trips during capacitive load inrush, eliminating need for external RC filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 0.8A typical - clamps output to safe level during overload without shutdown unless thermal limit exceeded |
| RDS(ON) | 90mΩ typical at 5V, 0.5A - enables low power loss and minimal voltage drop in 5V USB bus applications |
| Input Voltage Range | 2.7V–5.5V - supports full USB 2.0 VBUS tolerance and operation across wide supply rails |
| Rise Time | 0.6ms typical - soft-starts downstream loads to limit inrush current during hot-plug events |
| UVLO Threshold | 1.9V typical - prevents switch turn-on until stable input is established, critical for hot-insertion safety |
| Thermal Shutdown | +140°C trip / +115°C recovery - autonomous protection against sustained short-circuit or overload |
| FLG Blanking Time | 7ms typical - rejects transient over-current pulses from bulk capacitor charging, no external components needed |
Pinout & Package
AP2146MPG-13 is housed in an MSOP-8EP (Exposed Pad) package. The exposed pad must be externally connected to GND and thermal mass for optimal thermal performance but must not serve as primary electrical ground conduction path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1 | Channel 1 enable input | Active-low logic control; pulls low to activate OUT1; high-impedance when disabled |
| FLG1 | Channel 1 fault report | Open-drain output asserted low during over-current or over-temperature; includes 7ms deglitch |
| FLG2 | Channel 2 fault report | Independent open-drain fault indicator for OUT2; electrically isolated from FLG1 |
| EN2 | Channel 2 enable input | Active-low logic control for OUT2; allows independent sequencing of dual USB ports |
| OUT2 | Channel 2 output | Switched 5V output to downstream USB port; supports reverse current blocking when disabled |
| GND | Power and signal ground | Reference node for all internal circuits; connects to exposed pad for thermal conduction |
| IN | Main power input | Accepts 2.7V–5.5V VBUS; feeds both channels; requires local 0.01–0.1µF ceramic bypass |
| OUT1 | Channel 1 output | Switched 5V output to first USB port; independently controllable and monitorable via FLG1 |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable/fault paths | EN1/FLG1 and EN2/FLG2 allow per-port control and diagnostics in 2-port USB hubs |
| Reverse current blocking | Prevents backfeed from powered downstream devices into VBUS rail when switch is off |
| 7ms FLG deglitch | Hardware-based blanking eliminates false over-current alerts during capacitor charging transients |
| Low shutdown current | 1µA max - preserves system battery life in portable USB host applications |
| UL Recognized & IEC60950-1 CB certified | Validated safety compliance for end-equipment certification in consumer and computing markets |

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 |
|---|---|---|---|
| AP2156MPG-13 | Identical specs except EN1/EN2 are active-high instead of active-low | Requires inverted enable logic from host MCU; same pinout and thermal behavior | Select when system GPIOs drive enable signals high to activate switches |
| TUSB2036IPWR | USB 2.0 transceiver + integrated power switch; includes USB PHY and hub logic | Full 3-port hub IC with data switching; not a standalone power switch | Choose only if USB data routing and protocol handling are also required |
Compared with AP2146MPG-13, AP2156MPG-13 offers identical protection and timing but simplifies interface where active-high enables are preferred; TUSB2036IPWR adds full USB protocol functionality at the cost of higher integration complexity and reduced flexibility in discrete power control.

FAQ
What is the function of the exposed pad on the AP2146MPG-13 MSOP-8EP package?
The exposed pad serves as a thermal conduction path to PCB ground plane and must be soldered to a dedicated copper pour connected to GND. It improves θJA to 60°C/W but is not intended as the primary electrical ground return path-internal GND pin remains essential for signal reference.
Can AP2146MPG-13 drive a 500mA load continuously at 5V input?
Yes-its recommended maximum continuous load current is 0.5A per channel at 5V input and ambient temperatures up to +85°C. With 90mΩ RDS(ON), power dissipation is 22.5mW per channel, well within thermal limits when using proper PCB copper area per datasheet layout guidelines.
How does the 7ms FLG deglitch work during USB port hot-plug?
When a USB device with large input capacitance is inserted, momentary inrush current may exceed 0.8A. The internal deglitch circuit ignores such transients lasting less than ~7ms, preventing false FLG assertion. Only sustained over-current or thermal faults trigger the open-drain flag output.
Is AP2146MPG-13 compatible with USB Battery Charging (BC) 1.2 specification?
No-the AP2146MPG-13 implements only power switching and protection functions. It lacks BC1.2-specific D+/D− detection circuitry or dedicated charging port identification logic; it supports standard USB 2.0 power delivery only.
