Abstract: A system for determining angular position includes a dipole magnet having an axis of rotation, wherein the dipole magnet produces a magnetic field. A first magnetic field sensor produces a first output signal and a second magnetic field sensor produces a second output signal in response to the magnetic field. The magnetic field sensors are operated in a saturation mode in which the magnetic field sensors are largely insensitive to the field strength of the magnetic field. Thus, the first output signal is indicative of a first direction of the magnetic field and the second output signal is indicative of a second direction of the magnetic field. Methodology performed by a processing circuit entails combining the first and second output signals to obtain a rotation angle value of the magnet in which angular error from a stray magnetic field is substantially cancelled.

Abstract: A system for determining angular position includes a magnet having at least four poles and an axis of rotation, wherein the magnet produces a magnetic field. A first magnetic field sensor produces a first output signal and a second magnetic field sensor produces a second output signal in response to the magnetic field. The magnetic field sensors are operated in a saturation mode in which the magnetic field sensors are largely insensitive to the field strength of the magnetic field. Thus, the first output signal is indicative of a first direction of the magnetic field and the second output signal is indicative of a second direction of the magnetic field. Methodology performed by a processing circuit entails combining the first and second output signals to obtain a rotation angle value of the magnet in which angular error from a stray magnetic field is at least partially canceled.

Abstract: An open wire detection system and method are provided. A semiconductor device includes a first diode having an anode terminal coupled to a first terminal and a cathode terminal coupled to a second terminal. The first and second terminals are configured for connection to a first battery cell terminal by way of a first conductive path and a second conductive path. A detect circuit is coupled to the first diode and is configured to provide a first open wire indication when a first voltage across the first diode exceeds a first threshold.

Abstract: An integrated circuit includes a load circuit having multiple functional modules, a first voltage regulator configured to provide a supply voltage to the multiple functional modules, and a supply current monitoring circuit including a second voltage regulator and a current monitor, the second voltage regulator being configured to provide a test supply voltage. A switch matrix is interconnected between the first voltage regulator, the supply current monitoring circuit, and the functional modules. Each of the functional modules in successive order is a module under test, and the switch matrix is configured to disconnect the first voltage regulator from the module under test and connect the supply current monitoring circuit to the module under test such that the second voltage regulator provides the test supply voltage to the module under test and the current monitor measures a supply current of the module under test in response to the test supply voltage.
