Product details
Overview
AP2815DM-G1 from BCD Semiconductor is a 1.5A high-side power distribution switch with active-low enable and open-drain fault flag, built around an N-channel MOSFET with 60mΩ RDS(ON) at 5V, UVLO, soft-start, over-current fold-back protection, and thermal shutdown-designed for USB-compliant hot-plug power management in notebook motherboards and self-powered hubs.
For engineers reviewing the AP2815DM-G1 datasheet, AP2815DM-G1 pinout, AP2815DM-G1 application, or AP2815DM-G1 equivalent, this device supports precise current-limited (1.65–2.8A) USB VBUS switching, delivers <1µA shutdown current, integrates deglitched FLAG reporting for OCP/OTP faults, and operates across 2.7–5.5V with logic-level enable compatibility.
Technical Context
The AP2815DM-G1 implements a charge-pump–driven high-side N-MOSFET architecture to achieve low on-resistance while maintaining full control over load connection timing via integrated soft-start. Its active-low EN pin directly interfaces with USB host controllers without level-shifting.
Protection is multi-layered: current-limit fold-back reduces power dissipation during sustained short-circuit events; thermal shutdown triggers at 150°C with 30°C hysteresis; UVLO ensures operation only above 2.2V; and reverse-current blocking prevents backfeed when powered off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 60 mΩ @ VIN=5V - meets USB 2.0 voltage-drop spec under 1.5A load |
| Continuous Current | 1.5 A - guaranteed output capability with thermal derating up to 85°C ambient |
| Current Limit Range | 1.65–2.8 A - fold-back behavior limits peak power during shorts |
| Supply Current | 65 µA typ. - enables always-on monitoring without significant system quiescent load |
| Shutdown Current | 1.0 µA max - preserves battery life in portable USB host applications |
| FLAG Delay | 5–15 ms - provides noise-immune fault detection window before flag assertion |
| UVLO Threshold | 2.2–2.7 V - prevents erratic switching during brown-out or cold-start conditions |
Pinout & Package
AP2815DM-G1 is housed in an SOIC-8 package (4.9 × 6.0 × 1.25 mm), RoHS-compliant with G1 suffix, suitable for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference for internal circuitry and MOSFET source |
| 2, 3 | VIN | Input supply rail (2.7–5.5V); dual pins reduce trace resistance and improve current handling |
| 4 | EN | Active-low enable input; logic-compatible with 0–1.0V low, 1.6–5.5V high thresholds |
| 5 | FLAG | Open-drain fault indicator; pulls low on OCP, OTP, or UVLO fault; requires external pull-up |
| 6, 7, 8 | VOUT | Switched output; triple pins minimize voltage drop and thermal rise under 1.5A load |
Key Features
| Feature | Design Value |
|---|---|
| USB-compliant RDS(ON) | 60 mΩ ensures ≤75 mV drop at 1.5A, satisfying USB 2.0 VBUS regulation |
| Soft-start ramp | 500 µs turn-on time limits inrush current to prevent upstream supply sag or reset |
| Fold-back current limit | Reduces short-circuit current to ~1.12A after initial trip, lowering thermal stress |
| No reverse current flow | Internal body-diode blocking eliminates backfeed from VOUT to VIN when disabled |
| Deglitched FLAG | 10 ms typical delay filters transient noise, preventing false fault reporting |
Applications
| USB Bus-Powered Hubs | Hot-Plug Peripheral Ports |
|---|---|
Use Scenario: Power delivery to downstream USB devices from a bus-powered hub with strict VBUS drop and inrush constraints. IC Role / Device Role / Timing Role: High-side switch controlling VBUS path; enables/disables per-port power under host controller command via EN and reports faults via FLAG. Use Value: Guarantees 60mΩ on-resistance and soft-start ensure compliance with USB 2.0 electrical specs while protecting upstream port from overload. | Use Scenario: Adding hot-pluggable USB-C or Type-A ports to industrial docking stations requiring robust fault recovery. IC Role / Device Role / Timing Role: Isolates peripheral power domain; responds to EN edge with controlled ramp and asserts FLAG within 10ms of over-current event. Use Value: Fold-back current limiting and thermal shutdown prevent latch-up during repeated plug/unplug cycles in unattended systems. |
| Notebook Motherboard VBUS Control | Battery-Charger Input Switching |
Use Scenario: Managing USB VBUS power routing on thin-and-light laptop motherboards where space and thermal budget are constrained. IC Role / Device Role / Timing Role: High-side distribution switch with active-low EN synchronized to EC firmware; FLAG feeds fault status to embedded controller. Use Value: SOIC-8 footprint and 1.0µA shutdown current extend battery runtime during sleep states without sacrificing protection integrity. | Use Scenario: Enabling/disabling charging circuit input from shared 5V rail in dual-input (USB + adapter) portable chargers. IC Role / Device Role / Timing Role: Load switch isolating charger IC input; UVLO prevents activation below safe input voltage; no reverse current avoids discharging battery through charger path. Use Value: 2.7–5.5V operating range and reverse-current blocking ensure reliable handover between power sources without cross-conduction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS2051BDBVR | 1.5A rated, 70mΩ RDS(ON), active-high EN, no FLAG output | Lacks fault reporting; requires external comparator or MCU GPIO monitoring for OCP detection | Choose when FLAG signaling is unnecessary and active-high logic simplifies control interface |
| ON Semi NIS5132MN | 2A rated, 45mΩ RDS(ON), active-low EN, integrated FLAG with 1ms delay | Higher current rating and faster fault response; requires tighter layout due to MSOP-8 package | Prefer for higher-power USB PD sink paths or space-constrained designs needing lower on-resistance |
Compared with TPS2051BDBVR and NIS5132MN, AP2815DM-G1 offers balanced USB-compliant performance with integrated deglitched FLAG reporting and ultra-low shutdown current-ideal for cost-sensitive, thermally constrained notebook and hub designs requiring autonomous fault visibility.

FAQ
What is the function of the FLAG pin on AP2815DM-G1?
The FLAG pin is an open-drain output that actively pulls low during over-current, over-temperature, or under-voltage lockout conditions. It requires an external pull-up resistor and provides a deglitched signal with 5–15 ms delay to reject transient noise-enabling reliable fault detection by host microcontrollers without software debouncing.
Does AP2815DM-G1 support reverse current blocking?
Yes-AP2815DM-G1 blocks reverse current flow from VOUT to VIN when disabled, confirmed by a maximum reverse leakage of 1.0 µA at 5V. This prevents backfeed into upstream supplies or batteries, critical for dual-source systems like USB/battery-powered chargers.
How does the soft-start feature operate in AP2815DM-G1?
Soft-start limits inrush current by controlling the MOSFET gate ramp rate, resulting in a typical 500 µs output rise time from enable activation to 90% VOUT. This prevents voltage droop on shared input rails and avoids false triggering of upstream over-current protection during hot-plug events.
What is the difference between AP2815DM-G1 and AP2815AM-G1?
AP2815DM-G1 uses active-low enable (EN low = ON) and has no auto-discharge function, while AP2815AM-G1 uses active-high enable and includes an internal 13–50 Ω pull-down resistor on VOUT during shutdown to discharge output capacitance-critical for applications requiring rapid VOUT decay after disable.
