tle5011 Infineon Technologies Corporation, tle5011 Datasheet - Page 10

• Manufacturer Part Number: tle5011
• Description: Gmr Based Angular Sensor
• Manufacturer: Infineon Technologies Corporation

2.3
The internal stages of the TLE5011 are supplied with different voltage regulators.
• GMR Voltage Regulator VRG
• Analog Voltage Regulator VRA
• Digital Voltage Regulator VRD
Each voltage regulator has its own overvoltage and undervoltage detection circuits.
2.3.1
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 overvoltage and undervoltage detectors.
2.3.2
The analog voltage regulator supplies the analog parts.
• ADCs
• PLL (analog)
• VDD-Off comparator
• GND-Off comparator
•
The voltages are monitored in the VRA overvoltage and undervoltage detectors.
2.3.3
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 overvoltage and undervoltage detectors.
