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.
