Diodes Incorporated AP22980FCF10-7

Overview

AP22980FCF10-7 from Diodes Incorporated is a single-channel high-side load switch featuring tri-state soft-start control, active output discharge, and ultra-low 5.1 mΩ typical R_ON. It integrates an n-channel MOSFET supporting 6 A continuous current across 0.285 V to 5.5 V input voltage and 2.2 V to 5.5 V VBIAS supply, enabling use in SSD power rails, laptop core voltage sequencing, and server point-of-load switching.

For engineers reviewing the AP22980FCF10-7 datasheet, AP22980FCF10-7 pinout, AP22980FCF10-7 application, or AP22980FCF10-7 equivalent, key selection criteria include tri-state slew rate configurability (1/2/15 mV/µs), 60 µA typical quiescent current, 50 Ω integrated quick output discharge resistance, and thermal shutdown at +150°C junction temperature.

Technical Context

The AP22980FCF10-7 implements a charge-pump–assisted gate driver with tri-state detection logic on the SS pin to select one of three output slew rates without external components. Its VBIAS-supplied internal regulator powers control circuitry independently of VIN, enabling operation down to 0.285 V input while maintaining full functionality.

Thermal shutdown activates at +150°C with +25°C hysteresis, and the integrated 50 Ω discharge path connects VOUT to GND during disable or ON-delay states-even when VBIAS is invalid-ensuring no floating output condition. EN is active-HIGH with TTL/CMOS-compatible thresholds (0.7–0.9 V fall/rise).

FAQ

What is the minimum input voltage supported by the AP22980FCF10-7?

The AP22980FCF10-7 operates down to 0.285 V on the VIN pin, enabling direct integration into ultra-low-voltage domains such as sub-1 V I/O rails and advanced SoC power islands. This capability is enabled by its independent VBIAS-supplied gate driver architecture, which maintains full control functionality even when VIN is below traditional logic thresholds.

How does the tri-state SS pin configure slew rate without external components?

The SS pin detects three logic states-LOW (<0.5 V), HIGH (>1.05 V), and floating (>2 MΩ)-and latches the corresponding slew rate (1, 2, or 15 mV/µs) at first power-up when VBIAS becomes valid and EN goes high. No external resistors or capacitors are needed because internal comparators and charge-pump circuitry implement all three settings natively.

Does the Quick Output Discharge (QOD) function operate when VBIAS is unpowered?

Yes. The QOD circuit remains active and connects the 50 Ω internal discharge path between VOUT and GND whenever the switch is disabled (EN = LOW) or during tDON delay-even if VBIAS is absent or invalid. This ensures deterministic output discharge regardless of bias supply status, preventing floating conditions that could cause downstream logic glitches.

What thermal derating applies above +85°C ambient temperature?

At +105°C ambient, the maximum allowable power dissipation drops to 819 mW (calculated as (150 − 105)/55), limiting continuous 6 A operation unless PCB copper area and airflow exceed JEDEC 51-7 test board conditions. For sustained 6 A loads above +85°C, thermal vias under the exposed pad and ≥2 oz copper are mandatory to maintain junction temperature below +150°C.
