PGA41x-Q1 レゾルバ-デジタル・インターフェイス、内蔵エキサイタ電源およびアンプ付き

 

概要

The PGA411-Q1 device is a resolver to digital converter, with an integrated exciter-amplifier and boost-regulator power supply, that is capable of both exciting and reading the sine and cosine angle from a resolver sensor. The integration of the exciter amplifier and boost supply with protection in the PGA411-Q1 device enables cost reductions of the bill of materials (BOM) and space reductions on the printed circuit board (PCB) because of the elimination of most external and passive components.

The PGA411-Q1 device also has an internal clock for generating a sine wave used for sensor excitation. The architecture of the analog front-end (AFE) allows the user to output 10 bits or 12 bits of resolution for the angle position and velocity. Because of high integration, the PGA411-Q1 device has diagnostics and protection on each internal block inside the device. The integrated diagnostics monitor can signal a fault condition through a dedicated pin which can be used as a MCU interrupt. These features allow flexibility in both resolver sensor choice and platform scalability. Additionally, the PGA411-Q1 was designed according to the requirements of ISO 26262 for functional safety applications.
