Resolver-to-digital converter with integrated exciter amplifier and power supply  - PGA411-Q1

PGA411-Q1 (ACTIVE)

Resolver-to-digital converter with integrated exciter amplifier and power supply

 

Description

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.
