摘要： In described examples, an amplifier system (10) includes an input stage (12) configured to receive an input pulse signal and to generate a reference voltage pulse based on the input pulse signal. The amplifier system (10) also includes an amplifier stage (14) that receives at least one power voltage and is configured to amplify the reference voltage pulse and to provide pulse-shaping of the amplified reference voltage pulse based on a change of amplitude of the at least one power voltage resulting from an amplitude of the reference voltage pulse.

摘要： A current sink circuit is coupled to pull down a gate control node (GCN) (402) for an NMOS power FET (422) that controls an actuator (424). The current sink circuit includes first and second NMOS transistors (MNO, MN2) coupled in series between the GCN (402) and a lower rail. The first NMOS transistor (MNO) has a gate and drain coupled together through a resistor (RGSN). The current sink circuit also includes a control signal generation circuit (CSGC) (404) and a negative voltage blocking circuit (406). The CSGC (404) is coupled to receive at least one voltage input (e.g., any of DRN1, DRN2, DRN3, REGULATOR) and an ignition signal (IGNITION) and to provide a first control signal (CSl) and a second control signal (CS2). The negative voltage blocking circuit (406) is coupled to pass the first control signal from the CSGC (404) to the gate of the first NMOS transistor (MNO) and to block a negative voltage on the GCN (402) from reaching the CSGC (404). The second control signal (CS2) is coupled to the gate of the second NMOS transistor (MN2).

摘要： In described examples, an angular resolver system includes an imbalance detector (1600) for detecting degraded resolver output signals. The imbalance detector (1600) includes first (1602) and second (1604) power averaging circuits and a comparator circuit (1662, 1664, 1670). The first power averaging circuit (1602) includes a first integrator (1646) for generating over a first time window a first average power signal (Vcl) in response to resolver sensor output signals. The second power averaging circuit (1604) includes a second integrator (1648) for generating over a second time window a second average power signal (Vc2) in response to the resolver sensor output signals, where the first time window is longer than the second time window. The comparator circuit (1662, 1664, 1670) compares the first average power signal and the second average power signal and generates a fault signal (1670) when the first average power signal and the second average power signal differ by a selected voltage threshold (1654, 1658).
