Application Information
This chapter contains application information for the TS4956.
Figure 1 shows a typical
application schematic for the device.
2.1
IC bus description and operation
The TS4956 uses a serial bus, which conforms to the IC protocol, to control the chip’s
functions with two wires: clock and data. The clock line is uni-directional. The data line is bi-
directional (open-collector) with an outside chip pull-up resistor (typically 10kOhm). The
maximum clock frequency specified by the IC standard is 400kHz.
