Description
iC-TW2’s inter polation engine accepts two fully differential sensor bridges delivering sinusoidal input signals (SIN/COS) to produce a highly inter polated output signal. No fur ther external components are required. Single ended sensor signals are supported by tying the negative input terminal to a signal reference, usually VDD/2. iC-TW2 generates one index pulse for ever y input period. The position in respect to the start of the period as well as the width of the pulse is fully programmable. Index pulse position can be used in conjunction with the star tup mode to guarantee a desired phase relationship between A, B and index output pulse. There are four different output modes provided, including 3-phase commutation output for brushless DC motors. It is highly programmable to meet requirements for a wide range of applications. Two serial interfaces have been included to permit configuration of the device, also accessing an internal EEPROM. Both interfaces allow complete configuration of the device including transfer of setup and system data to register and EEPROM for non-volatile configuration. For an illustration of the inter polation function of the iC-TW2 see Figure 2 on page 10.
