Mini-USB interface IC
17 February 2010
Analogue, Mixed Signal, LSI
Freescale Semiconductor has developed a mini USB interface IC that enables a single mini USB connector to be used for external accessories including chargers, headsets, microphones and audio/data connections. In addition to saving valuable board space by eliminating the need for multiple connections, the MC34825 analog IC also lowers power consumption and extends battery life by supporting all-passive audio accessories such as stereo audio, microphone and cord remote control functionality.
The MC34825 uses intelligent switching to identify up to 32 different accessory types, such as headsets, microphones and chargers. It automatically identifies the attachment and informs the host system, switching the signal or setting the charge current based on the plugged-in charger. As a universal charging solution, the device supports multiple charger types including AC, DC and USB. The IC identifies the battery charger type and sets the charge current level accordingly. Additional battery charging features include up to 28 V OVP for the VBUS power input, low operating current (<10 μA at standby), a power-save mode and automatic detachment detection.
