Product details

Overview

AP22966DC8-7 from Diodes Incorporated is a dual-channel N-channel load switch IC with independently programmable slew rate per channel via external capacitors, 18 mΩ typical R_ON at 5 V bias, 6 A continuous current per channel, and operation from 0.8 V to 5.5 V input voltage - used for power rail sequencing in SSDs and ultrabooks.

For engineers reviewing the AP22966DC8-7 datasheet, AP22966DC8-7 pinout, AP22966DC8-7 application, or AP22966DC8-7 equivalent, key selection criteria include per-channel soft-start configurability, low quiescent current (45–60 µA), thermal performance in V-DFN3020-14, and compatibility with 1.2/1.8/2.5/3.3 V logic enables.

Technical Context

The AP22966 integrates two independent N-channel MOSFETs with internal charge pumps enabling full enhancement at low VIN (down to 0.8 V) and bias supply (VBIAS = 2.5–5.5 V). Each channel features dedicated slew-rate control (SS1/SS2) and quick output discharge (QOD) via internal 220–300 Ω discharge FET.

It supports independent enable control (EN1/EN2) compatible with TTL/CMOS logic levels, operates across –40°C to +85°C ambient, and delivers stable R_ON ≤26 mΩ over temperature and input voltage (0.8–5.5 V), with thermal resistance R_θJA = 47 °C/W on standard 2"×2" FR-4 PCB.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	0.8 V to 5.5 V per channel - enables direct integration into low-voltage core rails (e.g., 1.2 V, 1.8 V) and 5 V peripheral domains.
R_ON (Typical)	18 mΩ at VBIAS = 5 V, VIN = 5 V - limits conduction loss to <54 mW at 3 A, supporting high-efficiency power gating.
Max Continuous Current	6 A per channel - sufficient for powering high-current subsystems like NVMe SSD modules or display power rails.
Quiescent Current	45 µA (single channel active), 60 µA (both channels active) - extends battery life in always-on subsystems of portable computing.
Slew Rate Control	External capacitor on SS1/SS2 pins - allows precise tuning of VOUT rise time (e.g., 330–1720 µs) to suppress inrush and system voltage droop.
Quick Output Discharge	Internal 220–300 Ω discharge FET - ensures rapid VOUT discharge (<1 ms) upon disable, preventing floating outputs and latch-up risk.
Logic Enable Threshold	V_IH = 1.2 V min - supports direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V microcontroller GPIOs without level shifters.

Pinout & Package

V-DFN3020-14 package: 3.0 mm × 2.0 mm footprint, 0.8 mm height, exposed thermal pad (Pin 11 + PAD), RoHS-compliant, halogen-free.

Pin/Terminal	Circuit Role	Design Meaning
VIN1 (Pins 1, 2)	Channel 1 input supply	Accepts 0.8–5.5 V input; requires local 1 µF decoupling to limit VIN dip during turn-on transients.
EN1 (Pin 3)	Channel 1 enable input	Active-high TTL/CMOS-compatible control; must be driven - not left floating - to ensure deterministic switching.
VBIAS (Pin 4)	Bias supply for internal charge pump	2.5–5.5 V required to fully enhance N-MOSFETs at low VIN; powers gate drive circuitry for robust R_ON performance.
EN2 (Pin 5)	Channel 2 enable input	Independent active-high control identical to EN1; enables asynchronous power sequencing between rails.
VIN2 (Pins 6, 7)	Channel 2 input supply	Second independent input rail; same decoupling and voltage range requirements as VIN1.
VOUT2 (Pins 8, 9)	Channel 2 output	Source node of second N-MOSFET; connects to load; requires optional bulk capacitor (≥10 µF) for high-current loads.
SS2 (Pin 10)	Channel 2 slew rate control	Connect external capacitor to GND to set VOUT2 ramp time; 1000 pF yields ~1.6 ms rise (10–90%) at 5 V.
GND (Pin 11 + PAD)	Power and signal ground reference	Thermal pad must be soldered to PCB ground plane to achieve rated R_θJA = 47 °C/W and 2.7 W power dissipation.
SS1 (Pin 12)	Channel 1 slew rate control	Independent soft-start control identical to SS2; enables differential ramp timing for staggered power-up sequences.
VOUT1 (Pins 13, 14)	Channel 1 output	Source node of first N-MOSFET; electrically isolated from VOUT2 - supports dual independent power domains.

Key Features

Feature	Design Value
Dual independent load switches	Two fully isolated N-MOSFET channels with separate VIN/VOUT/EN/SS pins - enables concurrent or staggered power domain control without cross-talk.
Adjustable per-channel slew rate	External capacitor on SS1/SS2 sets VOUT rise time from ~330 µs to >13 ms - eliminates need for discrete RC networks and simplifies EMI-compliant inrush management.
Integrated quick output discharge (QOD)	220–300 Ω internal discharge FET automatically activates when EN = low - prevents residual charge hold-up and ensures safe hot-swap behavior.
Low-voltage logic compatibility	V_IH = 1.2 V min enables direct connection to 1.2 V I/O domains (e.g., modern SoC GPIOs), eliminating level-shifter components and board space.
Thermally optimized V-DFN3020-14	Exposed thermal pad + 6 mm² footprint delivers 2.7 W power handling and 47 °C/W R_θJA - supports 6 A/channel operation without external heatsinking in compact designs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel load switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS22965DSGR	Higher R_ON (24 mΩ typ), fixed slew rate, no VBIAS pin - relies on VIN for gate drive.	Limited to VIN ≥1.65 V; unsuitable for 0.8–1.2 V core rails where AP22966 maintains full R_ON spec.	Select when bias supply complexity must be avoided and input voltage stays ≥1.65 V.
RT9711CGJ5	Single-channel only, no QOD, higher I_Q (120 µA), no independent slew control.	Requires two devices for dual-rail use; lacks integrated discharge path - needs external resistor network.	Select for cost-sensitive single-rail applications where discharge timing is non-critical.

Compared with TPS22965DSGR and RT9711CGJ5, AP22966DC8-7 uniquely supports true 0.8 V operation with low R_ON, per-channel soft-start, and integrated QOD - making it the only option qualified for dual-rail, low-voltage, battery-critical systems like ultrabooks and SSDs.

FAQ

What is the minimum input voltage required for reliable operation of AP22966DC8-7?

The AP22966DC8-7 operates reliably down to 0.8 V on VIN1 and VIN2 when VBIAS is ≥2.5 V. At this minimum VIN, R_ON remains ≤27 mΩ (max) and t_ON is 748 µs (typ) with VBIAS = 2.5 V - verified across –40°C to +85°C ambient per DS36217 Rev. 3-2.

Can AP22966DC8-7 be used with a single 3.3 V supply instead of separate VIN and VBIAS rails?

No - VBIAS must be supplied independently and cannot be tied to VIN. The datasheet specifies VBIAS = 2.5–5.5 V regardless of VIN value. Using 3.3 V for both VIN and VBIAS is acceptable, but sharing one rail for both functions violates the internal charge pump architecture and degrades R_ON stability.

How does the Quick Output Discharge (QOD) function interact with external load capacitance?

The internal QOD FET (R_DIS = 220–300 Ω) discharges VOUT to <0.1 V within 1 ms for CL ≤100 nF. For larger loads (e.g., 10 µF bulk caps), discharge time scales linearly - e.g., ~3.3 ms for 10 µF - but remains effective for preventing floating states and meeting USB/CEC hot-unplug requirements.

Is the V-DFN3020-14 package lead-free and RoHS-compliant?

Yes - AP22966DC8-7 uses a fully lead-free, RoHS 2 (2011/65/EU) compliant V-DFN3020-14 package. It contains <900 ppm bromine, <900 ppm chlorine, and <1000 ppm antimony, meeting Diodes Incorporated's "Green" device definition per Note 3 in DS36217.
