Description
 sxm1991 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 TOPSwitch
or TinySwitch and other solutions employing traditional feedback
schemes.
  SXM1991   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.
SXM1991 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 CHY100 disables output voltage adjustment to
ensure safe operation with legacy 5 V only USB PDs.
