Diodes Incorporated AP2810AM-G1

Overview

AP2810AM-G1 from BCD Semiconductor is a 1.0A high-side power distribution switch with integrated N-channel MOSFET (R_DS(ON) = 60 mΩ @ 5V), enable control, and open-drain fault flag output. It provides over-current protection with fold-back, thermal shutdown, under-voltage lockout (UVLO), and soft-start for USB-compliant hot-plug applications in notebook and motherboard power rails.

For engineers reviewing the AP2810AM-G1 datasheet, AP2810AM-G1 pinout, AP2810AM-G1 application, or AP2810AM-G1 equivalent, key selection criteria include its active-high enable logic (Condition A), auto-discharge function, SOIC-8 Green package, and guaranteed 1.0A continuous load capability with 1.1–2.1A current limit range.

Technical Context

The AP2810AM-G1 implements a charge-pump–driven high-side N-MOSFET switch with integrated protection logic. Its UVLO threshold (2.2–2.7V) ensures turn-on only above valid input voltage, while fold-back current limiting reduces power dissipation during sustained short-circuit events.

It features dual-stage fault response: fast flag assertion (5–15 ms delay) on over-current or over-temperature, plus automatic thermal shutdown at 150°C with 30°C hysteresis. The internal discharge resistor (100–200 Ω) actively pulls VOUT low after disable, eliminating reverse current (≤1.0 µA) when powered off.

FAQ

What is the enable logic polarity of AP2810AM-G1?

The AP2810AM-G1 uses active-high enable logic (Condition A), with V_ENH threshold between 1.6V and 5.5V. When EN is pulled high above 1.6V, the switch turns on; below 1.0V (V_ENL), it disables. This matches standard 3.3V GPIO outputs without level-shifting.

Does AP2810AM-G1 require an external pull-up on the FLAG pin?

Yes - FLAG is an open-drain output and must be pulled up externally (typically to 3.3V or 5V). The datasheet specifies a 5mA sink capability and 35–70mV low-level voltage, so a 10kΩ pull-up ensures reliable logic-low detection while minimizing current draw during fault events.

Can AP2810AM-G1 drive loads beyond 1.0A continuously?

No - it is rated for 1.0A continuous output current. While its current limit window spans 1.1–2.1A, sustained operation above 1.0A risks thermal shutdown due to junction temperature rise. Derating is required above +60°C ambient; SOIC-8 θ_JA is 135°C/W, limiting practical continuous load to ~0.7A at 85°C ambient.

How does the auto-discharge function operate after shutdown?

Upon EN deactivation, an internal 100–200 Ω resistor connects VOUT to GND, actively discharging output capacitance. This prevents floating voltages, eliminates reverse current (≤1.0 µA), and ensures safe hot-removal - critical for USB and PCIe hot-plug compliance where residual VBUS could damage connectors or hosts.
