STUSBCD01BJR STMicroelectronics

STUSBCD01B USB charger detection interface Features Capable of detecting dedicated USB chargers and host chargers (current sink and dedicated methods) Operates with V supply voltage ranging BAT from 2.2 V to 4.5 V Active high open drain hardware detection pin Flip-Chip 12 (1.6 x 1.2 mm) (DETECT) GPIO control interface 1.6 V - 2.8 V interface voltage range (V ) IO V voltage 6 V clamping circuit BUS Operation is controlled through three general Low DP-DM input capacitance purpose I/O pins a hardware open drain ESD: HBM 2 kV, CDM 500 V on every pin detection output is also available. 12 bumps Flip-Chip package, 1.6 x1.2 mm, An internal regulator provides the 1.8 V supply pitch 0.4 mm, max thickness 0.60 mm, voltage for the internal blocks and state machine Halogen free RoHS compliant package while a clamping device prevents V voltage BUS from going over 6 V (typ.). Applications The STUSBCD01B is available in a 12 bumps Flip-Chip 0.4 mm pitch package. Mobile phones PDAs, MP3 players Description The STUSBCD01B is a USB charger detection IC which can detect dedicated USB chargers, Host/Hub chargers or standard host ports connected to the USB DP/DM data lines. The device implements two different detection methods in order to be able to distinguish between a dedicated charger and a Host/Hub charger. Table 1.
