EC49024

SOP-8L

General Description

EC49024 is designed to support Quick Charge QC

2.0 (QC2.0) specifications. It is a low-cost solution to

support QC2.0 functions. EC49024 incorporates all

necessary functions to add QC 2.0 capability to

standard Adaptor designs, Portable Battery designs,

and Car-charger designs.

EC49024 supports the full output voltage range of

either Class A or Class B. Optionally Class B can be

inhibited for

protecting the battery charger

from

accidental damage.

EC49024

automatically

detects

whether

a

connected Powered Device (PD) is QC2.0 capable

before enabling output voltage adjustment. If a PD that

is not compliant to QC2.0 is detected the EC49024

disables output voltage adjustment to ensure safe

operation with legacy 5 V only USB PDs.
