Diodes Incorporated AP2810CMM-G1

Overview

AP2810CMM-G1 from BCD Semiconductor is a 1.0A integrated high-side power distribution switch with active-low enable and open-drain fault flag, designed for USB-compliant hot-plug power control. It features 60mΩ R_DS(ON) at 5V, 2.7–5.5V operating range, 1.1–2.1A current limiting, thermal shutdown, and UVLO-enabling robust USB bus/hub power management in notebooks and motherboards.

For engineers reviewing the AP2810CMM-G1 datasheet, AP2810CMM-G1 pinout, AP2810CMM-G1 application, or AP2810CMM-G1 equivalent, key selection criteria include active-low enable logic, auto-discharge capability, MSOP-8 footprint compatibility, fault flag timing (5–15ms delay), and compliance with USB voltage-drop and inrush-current requirements.

Technical Context

The AP2810CMM-G1 integrates an N-channel MOSFET with charge pump gate drive, enabling low-R_DS(ON) operation without external bias. Its fold-back short-circuit protection reduces power dissipation during sustained overloads, while thermal shutdown triggers at 150°C with 30°C hysteresis to prevent latch-up.

UVLO ensures turn-on only above 2.2–2.7V input, and the open-drain FLAG pin asserts low within 15ms of OCP or OTP events. The device supports soft-start via internal slew-rate control, limiting inrush current without requiring external RC networks.

FAQ

What is the function of the FLAG pin on AP2810CMM-G1?

The FLAG pin is an open-drain output that pulls low within 5–15ms when over-current or over-temperature conditions occur. It requires an external pull-up resistor to the host controller's logic rail and serves as a hardware interrupt signal-enabling immediate firmware response without polling. It remains asserted until the fault condition clears and the device recovers automatically after thermal cooldown or current normalization.

Does AP2810CMM-G1 support reverse current blocking?

Yes-AP2810CMM-G1 blocks reverse current flow from VOUT to VIN when disabled, with measured leakage of ≤1.0µA at VOUT > VIN. This eliminates the need for an external blocking diode in battery-charger or dual-supply applications, reducing power loss and board space. The feature is inherent to its N-channel MOSFET architecture with controlled gate drive sequencing.

How does the auto-discharge function operate in AP2810CMM-G1?

When the EN pin is deasserted (driven high), AP2810CMM-G1 activates an internal 100–200Ω pull-down between VOUT and GND, discharging residual voltage on downstream capacitors within milliseconds. This prevents floating VBUS lines that could cause enumeration failures or ESD stress in USB hubs-no external components required, unlike variants without auto-discharge (e.g., AP2810BMM-G1).

What is the recommended input capacitor value for AP2810CMM-G1?

BCD recommends a minimum 2.2µF ceramic input capacitor for stable operation under normal conditions. If frequent short-to-ground events occur at VOUT (e.g., in ruggedized docking stations), a larger 22µF input capacitor is advised to limit voltage sag and ensure reliable UVLO recovery. Placement must be within 5mm of VIN/GND pins to minimize loop inductance and suppress high-frequency ringing.
