3 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,
designed according to the requirements of ISO 26262
for functional safety applications.
