LPS100 4.0-6.0 5/9/12/20 1 Fully supports QC2.0 specification. Adjacent pin short-circuit fault SOT8

Charger Interface Physical Layer IC

General Description

LPS100 is a low-cost USB high-voltage dedicated charging port (HVDCP) interface IC for the Quick Charge 2.0 specification. It incorporates all necessary functions to add Quick Charge 2.0 capability to Power Integrations’ switcher ICs such as TOP Switch or Tiny Switch and other solutions employing traditional feedback schemes. LPS100 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. LPS100 automatically detects whether a connected Powered Device (PD) is Quick Charge 2.0 capable before enabling output Voltage adjustment. If a PD not compliant to Quick Charge 2.0 is detected the LPS100 disables output Voltage adjustment to ensure safe operation with legacy 5V only USB PDs.
