Product details

Overview

AP22908W6-7 from Diodes Incorporated is a single P-channel MOSFET high-side load switch with slew-rate control, designed for power sequencing and inrush current suppression in portable electronics. It operates from 1.08V to 3.6V input, delivers up to 1.5A continuous output current, features 28mΩ typical R_DS(ON) at 3.6V, and consumes only 0.05µA quiescent current. Its active-high ON pin (VIH min = 0.9V) and integrated 80Ω output discharge FET enable clean power rail control in battery-powered systems.

For engineers reviewing the AP22908W6-7 datasheet, AP22908W6-7 pinout, AP22908W6-7 application, or AP22908W6-7 equivalent, key selection criteria include input voltage range compatibility (1.08–3.6V), slew-controlled turn-on time (110µs typ. at 3.6V), low R_DS(ON) across voltage rails, thermal performance (R_θJA = 165°C/W in SOT26), and output discharge capability for fast rail collapse.

Technical Context

The AP22908W6-7 integrates a P-channel MOSFET with internal slew-rate control circuitry that limits dV/dt at VOUT during turn-on to suppress inrush current into capacitive loads. Its gate drive is optimized for low-voltage operation down to 1.08V, maintaining functional VIH (0.9V) and VIL (0.38V) thresholds across temperature.

It includes an integrated discharge FET (R_DIS = 80Ω typ.) activated when ON = low, ensuring rapid VOUT discharge to ground. Thermal design is constrained by its SOT26 package's 606mW maximum power dissipation and 165°C/W junction-to-ambient thermal resistance under JEDEC high-K board conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	1.08V to 3.6V - supports direct interface with 1.2V, 1.8V, 2.5V, 3.3V, and 3.6V logic and power rails.

Pinout & Package

The AP22908W6-7 is housed in a standard green SOT26 package (3.0mm × 2.8mm × 1.1mm), featuring six leads in a compact surface-mount outline with matte tin-plated terminations.

Pin/Terminal	Circuit Role	Design Meaning
VIN (Pins 4, 6)	P-channel MOSFET source	High-side input rail connection; requires 1µF local decoupling to GND for stability.

GND (Pins 2, 5)	Power and signal reference	Common return path for input/output bypass caps and ON control logic; must be low-impedance.
ON (Pin 3)	Enable control input	Active-high digital input; VIH ≥ 0.9V ensures reliable turn-on across voltage and temperature.

Key Features

Feature	Design Value
Slew-rate controlled turn-on	105µs typical rise time at 3.6V - eliminates need for external RC snubbers in USB/SDIO power rails.
Integrated output discharge	80Ω on-resistance - actively pulls VOUT to GND within microseconds after disable, preventing backfeed.
Ultra-low IQ operation	0.05µA typical - extends battery life in always-on sensor nodes and wearable sleep-mode states.

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
TCK107AG,314 (Toshiba)	Lower R_DS(ON) (18mΩ @3.6V), but higher IQ (0.15µA); no integrated discharge FET.	Requires external 100Ω discharge resistor; better for ultra-low-loss 3.3V rails where discharge speed is secondary.	Select when minimizing conduction loss is critical and board space allows discrete discharge circuitry.
TPS22916BLYFPR (TI)	Higher voltage range (0.75–5.5V), lower R_DS(ON) (17mΩ @3.6V), but larger 1.05mm × 1.45mm DSBGA package.	Supports wider input range including 0.9V LPDDR cores; less suitable for legacy 0.87mm × 0.87mm CSP footprints.	Select for next-gen ultra-low-voltage SoC interfaces requiring <0.9V operation and tighter R_DS(ON) tolerance.

Compared with TCK107AG,314 and TPS22916BLYFPR, the AP22908W6-7 uniquely balances ultra-low IQ (0.05µA), integrated discharge, and SOT26 compatibility-making it optimal for cost-sensitive, space-constrained portable designs where standby power and rail collapse timing are co-critical.

FAQ

What is the minimum input voltage required for reliable operation of AP22908W6-7?

The AP22908W6-7 is specified to operate down to 1.08V input, with guaranteed functionality including VIH = 0.9V and R_DS(ON) = 112mΩ (typ.) at 1.08V. Below this threshold, turn-on may become inconsistent due to insufficient gate overdrive, and R_DS(ON) increases significantly-so 1.08V is the validated lower limit for production use.

Does AP22908W6-7 require external components for basic operation?

Yes-two external capacitors are mandatory: a 1µF ceramic capacitor between VIN and GND, and a 0.1–1µF ceramic capacitor between VOUT and GND. These stabilize input supply noise and absorb load transients. No external resistors or diodes are needed for slew control or discharge, as both functions are fully integrated.

Can AP22908W6-7 be used in automotive applications?

The AP22908W6-7 is not AEC-Q100 qualified. While it operates across –40°C to +85°C and meets JEDEC moisture sensitivity level 1, Diodes explicitly states that automotive-grade versions (with PPAP, IATF 16949 manufacturing, and AEC qualification) require separate part numbers and consultation with their automotive team-this SOT26 variant is intended for commercial portable electronics only.

How does the output discharge function behave during power-down?

When the ON pin is driven low, the internal discharge FET activates immediately, connecting VOUT to GND through an 80Ω (typ.) on-resistance. This discharges typical 100nF–1µF output capacitances in 8–80µs, preventing back-powering of upstream sources or unintended biasing of downstream ICs-critical for clean power sequencing in multi-rail systems.
