Diodes Incorporated AP2815DMM-G1

Overview

AP2815DMM-G1 from BCD Semiconductor is a 1.5A high-side power distribution switch with active-low enable and open-drain FLAG output, designed for USB-compliant hot-plug power management. It features 60mΩ R_DS(ON) at 5V, 2.7–5.5V operating range, integrated soft-start, over-current protection with fold-back, thermal shutdown, and UVLO-enabling robust USB bus/self-powered hub and notebook motherboard power rail control.

For engineers reviewing the AP2815DMM-G1 datasheet, AP2815DMM-G1 pinout, AP2815DMM-G1 application, or AP2815DMM-G1 equivalent, this device is selected for precise current-limited high-side switching in space-constrained USB peripheral power domains where fault flagging, low quiescent current (65µA), and no reverse current during shutdown are critical design requirements.

Technical Context

The AP2815DMM-G1 implements an N-channel MOSFET high-side switch driven by an internal charge pump, enabling full enhancement at low input voltages down to 2.7V. Its current-limit threshold (1.65–2.8A) is internally trimmed and temperature-compensated, while fold-back short-circuit response reduces power dissipation during sustained overloads.

FLAG output provides deglitched, open-drain fault signaling for OCP or OTP events with 5–15ms delay; enable logic is active-low without auto-discharge per ordering code 'D'. UVLO (2.2–2.7V with 0.2V hysteresis) ensures clean turn-on only above valid supply thresholds.

FAQ

What is the function of the FLAG pin on AP2815DMM-G1?

The FLAG pin is an open-drain output that goes low during over-current or over-temperature fault conditions. It requires an external pull-up resistor and provides deglitched, 5–15ms-delayed signaling to alert the host controller-enabling software-driven recovery or port disable without hardware intervention.

Does AP2815DMM-G1 support reverse current blocking when disabled?

Yes. When disabled, AP2815DMM-G1 blocks reverse current from VOUT to VIN with leakage under 1.0 µA. This prevents backfeeding into upstream supplies-a critical requirement for USB OTG and multi-rail systems where power domains must remain isolated.

How does the soft-start feature operate in AP2815DMM-G1?

Soft-start is implemented via internal slew-rate control of the gate drive, limiting output voltage rise time to ~500 µs. This caps inrush current during turn-on, protecting input capacitors and upstream regulators-especially important in USB hubs with multiple parallel ports sharing one input rail.

What is the significance of the 'D' suffix in AP2815DMM-G1?

The 'D' denotes active-low enable logic without auto-discharge functionality. Unlike variants 'A' or 'C', this version does not actively pull VOUT low after disable-allowing external hold-up capacitors to sustain downstream loads briefly, which is useful in controlled hot-unplug scenarios.
