70.3 Electrical Accessories integrating a MagSafe Charger Module shall comply with the electrical requirements in this section. 70.3.1 Power Accessories integrating a MagSafe Charger Module shall provide power from either: ● An internal power supply. ● An external USB power source. If the accessory integrates an Internal Power Supply (page 629), it: ● May accept external power using any of the following integrated connectors so long as the accessory actively conditions and regulates the power: ● USB-C Receptacle (page 831). ● USB-C Plug (page 829). ● Non-USB connector. ● May consume some of the external power for its own purposes so long as all MagSafe Charger Module power requirements are met. If the accessory relies on an External USB Power Source (page 629) to provide power to the MagSafe Charger Module and does not contain its own internal power supply, it: ● Shall connect to the external USB power source using a USB-C Plug (page 829). ● Shall not consume any power from the external USB power source. ● Shall not monitor or modify the USB D+/D- or CC signals from the external USB power source. The accessory shall integrate reverse voltage protection (RVP) between the MagSafe Charger Module power and ground. The MagSafe Charger Module maximum average current is 2.5 A at 9 V. The current is further limited based on the power source identification (for example, USB PD, USB D+/D- resistor network values, or USB enumeration). The MagSafe Charger Module includes: ● Overvoltage protection (OVP). ● Overcurrent protection (OCP). ● Overtemperature protection (OTP). ● Foreign object detection (FOD). 2022-10-26 | Copyright © 2022 Apple Inc.

Apple MagSafe Charger Module 70.3 Electrical 70.3.1.1 Internal Power Supply A MagSafe Charger Module powered by an accessory's internal power supply shall be configured to operate in 9 V mode using the PowerMode (page 635) command. After configuration, the USB D+/D- and CC pads shall be left Not Connected (NC) as specified in Pads and Assignments (page 630). The accessory's internal power supply for the MagSafe Charger Module shall: ● Support a load of 0 W to 20 W (2.22 A at 9 V). Apple recommends supporting up to 22.5 W (2.5 A at 9 V). ● Regulate input voltage at the PWR pad of the MagSafe Charger Module to 9.0 V ±5% under any supported load. ● Hold PWR ripple below: ● 180 mVpp from 1 kHz to 4 kHz under any supported load. ● 400 mVpp below 1 kHz or above 4 kHz under any supported load. ● Have a PWR rise time (10% to 90%) of less than 10 ms during power on. ● Tolerate a transient current up to 4.5 A for up to 1 ms. 70.3.1.2 External USB Power Source A MagSafe Charger Module powered by an external USB power source shall be configured to operate in USB mode using the PowerMode (page 635) command. Accessories relying on an external USB power source to provide power to the MagSafe Charger Module shall: ● Have maximum 112 mΩ round trip DCR (USB VBUS to Ground) between the MagSafe Charger Module connector and the accessory's USB-C Plug (page 829). ● Have a VBUS DCR less than 92 mΩ assuming 1 m cable. ● Have a GND DCR less than 20 mΩ assuming 1 m cable. ● Have a D+/D- DCR less than 1013 mΩ assuming 1 m cable. ● Have a CC DCR less than 5580 mΩ assuming 1 m cable. ● Pass the USB-IF Full Speed signal quality test. See Full Speed USB (page 826) and Full Speed USB (page 837). ● Meet the USB-IF inrush current specification of 51.5 μC. See the USB-IF Full and Low Speed Electrical and Interoperability Compliance Test Procedure and Gold Suite Test Procedure for USB-IF test procedures. If the accessory implements additional OCP, the maximum round trip DCR shall include the on-resistance of the OCP circuit. If the accessory bundles an external USB power source, it shall provide at least 20 W (2.22 A at 9 V). Apple recommends supporting up to 22.5 W (2.5 A at 9 V). 2022-10-26 | Copyright © 2022 Apple Inc. All Rights Reserved. 629 70.

Care should be taken to ensure any connection to the GND pad does not short to the enclosure. Signals from the USB D+ and D- pads shall be routed as a differential pair. All pads support up to 20 AWG wires. 70.3.3 ESD Accessories shall ensure there is no arcing path to the MagSafe Charger Module housing. Air gaps between the accessory housing and the module should be covered using a non-conductive coating or other material to prevent arcing. If air gaps cannot be covered, the module's metal housing near the gap should be insulated with a coating, such as: ● >250 μm polyurethane. ● >100 μm parylene. 70.3.4 EMC Accessories integrating the MagSafe Charger Module should be designed for Electromagnetic Compatibility (EMC) (page 328). 2022-10-26 | Copyright © 2022 Apple Inc. All Rights Reserved. 630 70. Apple MagSafe Charger Module 70.3 Electrical The wires connected to the module pads should be part of a shielded cable. The shield and drain/ground wires should be tied together and connected to the GND pad of the module. The shield shall not be connected to the module housing. Avoid coupling from the accessory enclosure to the module housing. Cable bundles should be physically isolated from the module housing to minimize unwanted coupling. A spacer or absorber material may be placed between the cable bundle and the module housing for additional isolation. The material should be 1 mm thick and should be one of the following: ● RF absorber material effective at 30-100 MHz. ● Spacer w…
