Internal Power Supply
The internal stages of the TLE5010 are supplied with different voltage regulators. Each
voltage regulator has its own over- and undervoltage detection circuits.
GMR Voltage Regulator VRG (VDDG-Voltage)
The GMR voltage regulator supplies all GMR parts.
• GMR Bridges
• Test Voltages for Angle Test
• ADC Reference Voltage
The voltages are monitored in the VRG over- and undervoltage detectors.
Analog Voltage Regulator VRA (VDDA-Voltage)
The analog voltage regulator supplies the analog parts.
• ADCs
• PLL (analog)
• VDD-Off comparator
• GND-Off comparator
V
•
Overvoltage detection
DD
The voltages are monitored in the VRA over- and undervoltage detectors.
Digital Voltage Regulator VRD (VDDD-Voltage)
The digital voltage regulator supplies all digital parts.
• Comb filters, FIR filters and Low Pass filter
• PLL (digital)
• Control FSM with Bitmap
• SSC -Interface
• Counters (Reset, FSYNC, FCNT)
The voltages are monitored in the VRD over- and undervoltage detectors.
