Functional Block Description

Internal Power Supply (PMU)

The internal blocks of the TLE5014 are supplied from several voltage regulators:

• GMR Voltage Regulator, VRS

• Analog Voltage Regulator, VRA

• Digital Voltage Regulator, VRD

These regulators are directly connected to the supply voltage VDD.

Oscillator and PLL (Clock)

The digital clock of the TLE5014 is given by the Phase-Locked Loop (PLL), which is fed by an internal oscillator.

SD-ADC

The Sigma-Delta Analog-Digital-Converters (SD-ADC) transform the analog GMR voltages and temperature

voltage into the digital domain.

Digital Signal Processing Unit ISM_ALG

The Digital Signal Processing Unit ISM_ALG contains the:

• Intelligent State Machine (ISM), which does error compensation of offset, offset temperature drift,

amplitude synchronicity and orthogonality of the raw signals from the GMR bridges.

• COordinate Rotation DIgital Computer (CORDIC), which contains the trigonometric function for angle
