Product Description
Overview
The TLE5012 is a 360° angle sensor that detects the orientation of a magnetic field. This is achieved by measuring sine and cosine angle components with monolithic integrated Giant Magneto Resistance (iGMR) elements. High precision angle values are achieved over temperature and lifetime using internal autocalibration algorithm. Data communications are accomplished with a bi-directional SSC Interface that is SPI compatible. The absolute angle value and other values are transmitted via SSC or via a Pulse-Width-Modulation (PWM) Protocol. Also the sine and cosine raw values can be read out. These raw signals are digitally processed internally to calculate the angle orientation of the magnetic field (magnet). The TLE5012 is a precalibrated sensor. The calibration parameters are stored in laser fuses. At start-up the values of the fuses are written into Flip-Flops, where these values can be changed by the application specific parameters. The TLE5012-E0318 and TLE5012-E0742 are especially configured in a Hall-Switch emulation mode for motors with three or seven pole pairs. Online diagnostic functions are provided to ensure reliable operation.

Functional Description
General
The GMR sensor is implemented using vertical integration. This means that the GMR sensitive areas are integrated above the logic portion of the TLE5012 device. These GMR elements change their resistance depending on the direction of the magnetic field. Four individual GMR elements are connected to one Wheatstone Sensor Bridge. These GMR elements sense one of two components of the applied magnetic field: • • X component, Vx (cosine) or the Y component, Vy (sine)
The advantage of a full-bridge structure is that the amplitude of the GMR signal is doubled and temperature effects cancel out each other.

Sensitive Bridges of the GMR Sensor
Note: In Figure 1, the arrows in the resistors symbolize the direction of the Reference Layer, which is used for the further explanation. The output signal of each bridge is only unambiguous over 180° between two maxima. Therefore two bridges are orientated orthogonally to each other to measure 360°. With the trigonometric function ARCTAN, the true 360° angle value can be calulated which is represented by the relation of X and Y signals. Because only the relative values influence the result, the absolute size of the two signals is of minor importance. Therefore, most influences to the amplitudes are compensated.

Note: The thermal resistances listed in Table 20 “Package Parameters” on Page 55 must be used to calculate the corresponding ambient temperature. Calculation of the Junction Temperature The total power dissipation PTOT of the chip increases its temperature above the ambient temperature. The power multiplied by the total thermal resistance RthJA (Junction to Ambient) leads to the final junction temperature. RthJA is the sum of the addition of the values of the two components Junction to Case and Case to Ambient.
RthJA = RthJC + RthCA TJ = TA + ∆T ∆T = RthJA × PTOT = RthJA × (VDD × I DD + VOUT × I OUT )
Example (assuming no load on Vout):

(IDD, I OUT > 0, if direction is into IC)
VDD = 5V I DD = 12mA K ∆T = 150 × 5[V ]× 0.012[A] + 0[VA] = 9 K W
For moulded sensors, the calculation with RthJC is more adequate.

Angle Performance
After internal calculation the sensor has a remaining error, as shown in Table 7. The error value refers to BZ = 0mT and the operating conditions given in Table 3 “Operating Range” on Page 17. The overall angle error represents the relative angle error. This error describes the deviation to the reference line after zero angle definition.

Autocalibration The autocalibration enables online parameter calculation and reduces therefore the angle error due to misalignments. After start-up the parameters out of the fuses get loaded into flip-flops. The TLE5012 updates these parameters after a full revolution. The update can be chosen within the Autocalibration Mode (AUTOCAL) bit. It is possible to do the update after every 22.5°, 11.25° or after tupd.

Signal Processing
The signal path of the TLE5012 is depicted in Figure 11. It consists of the GMR-bridge, ADC, filter and angle calculation. Depending on the filter configuration a different total delay time is achieved. Additional to this delay time, the delay time of the interface has to be considered. The delay time leads to an additional angle error at higher speeds. With enabling the prediction, the signal delay time will be reduced (Figure 12).

Clock Supply (CLK Timing Definition)
If the external clock supply is selected, the clock signal input ’CLK’ must fulfill certain requirements which are described in the following: • • • The high or low pulse width must not exceed the specified values, because the PLL needs a minimum pulse width and must be spike filtered. The duty cycle factor should be 0.5 but can deviate to the values limited by tCLKh(f_min) and tCLKl(f_min). The PLL is triggered at the positive edge of the clock. If more than 2 edges are missing, a chip reset is generated automatically.

SSC Bit Ordering (Read Example)
The data communication via SSC interface has the following characteristic: The data transmission order is “Most Significant Bit (MSB) first”. Data is put on the data line with the rising edge on SCK and read with the falling edge on SCK. The SSC Interface is word-aligned. All functions are activated after each transmitted word. A “high” condition on the negated Chip Select pin (CSQ) of the selected TLE5012 interrupts the transfer immediately. The CRC calculator is automatically reset. After changing the data direction, a delay (twr_delay) has to be considered before continuing the data transfer. This is necessary for internal register access. Every access to the TLE5012 with the number of data (ND) ≥ 1 is performed with address auto-increment. At an overflow at address 3FH the transfer continuous at address 00H. With ND = 0 no auto-increment is done and a continuously readout of the same address can be realized. Afterwards no Safety Word is send and the transfer ends with high condition on CSQ. After every data transfer with ND ≥ 1 the 16 bit Safety Word will be appended by the selected TLE5012. At a rising edge of CSQ without data transfer before (no SCK-pulse), the update-registers are updated with according values. After sending the Safety Word the transfer ends. To start another data transfer, the CSQ has to be deselected once for tCSoff. The SSC is default Push-Pull. The Push-Pull driver is only active, if the TLE5012 has to send data, otherwise the Push-Pull is disabled for receiving data from the microcontroller.
Cyclic Redundancy Check (CRC) • • • • • • This CRC is according to the J1850 Bus-Specification. Every new transfer resets the CRC generation. Every Byte of a transfer will be taken into account to generate the CRC (also the sent command(s)). Generator-Polynomial: X8+X4+X3+X2+1, but for the CRC generation the fast-CRC generation circuit is used (see Figure 20) The remainder of the fast CRC circuit is initial set to ’11111111B’. Remainder is inverted before transmission.

Pulse Width Modulation Interface
The Pulse Width Modulation (PWM) Interface can be selected by connecting CLK to VDD. The PWM update rate can be programmed within the register 0EH (IFAB_RES) in following steps: • • • • 0.25 kHz with 12 bit resolution 0.5 kHz with 11 bit resolution 1.0 kHz with 10 bit resolution (default) 2.0 kHz with 9 bit resolution
PWM uses a square wave with constant frequency whose duty cycle is modulated resulting in an average value of the waveform. Figure 21 shows the principle behavior of a PWM with different duty cycles and the definition of timing values. The duty cycle of a PWM is defined by following general formulas:
Duty Cycle =
ton t PWM
t PWM = t on + toff f PWM = 1 t PWM
(3)
The range between 0 - 6.25% and 93.75 - 100% is used only for diagnostic purposes. More details are given in Table 16.

Hall Switch Mode
The Hall Switch Mode (HSM) within the TLE5012 allows to emulate the output of three Hall switches. Hall switches are often used in electrical commutated motors to get information of the rotor position. With these three output signals the motor will be commutated in the right way. Depending on the used pole pairs of the rotor, different amount of electrical periods have to be realized. This is selectable within 0EH (HSM_PLP). Within the TLE5012E0318 three polepairs and within the TLE5012-E0742 seven polepairs are fused. Figure 22 depicts the three output signals with the relationship between electrical angle and mechanical angle. The mechanical 0° point is always used as reference.

Incremental Interface
The Incremental Interface (IIF) uses an up/down counter of a microcontroller for the angle transmission. The synchronization is done by the parallel active SSC-Interface. The angle value read out by the SSC-Interface can be compared with the stored counter value. In case of a non-synchronization, the microcontroller add the difference to the actual counter value to synchronize the TLE5012 with the microcontroller. The resolution of the IIF can be selected within the interface mode4 register (MOD_4) under IFAB_RES. A/B Mode The phase shift between phase A and B indicates a clockwise (B follows A) or a counterclockwise (A follows B) rotation of the magnet.

ADC Test Vectors
It is possible to feed the ADCs with appropriate values to simulate a certain magnet position and other GMR effects. This test can be activated within SIL register (ADCTV_EN). With ADCTV_Y and ADCTV_X the vector length can be adjusted like Figure 26. The values are generated with resistors on the chip. The following X/Y ADC values can be programmed: • • • • 4 points, circle amplitude = 70% (0°,90°, 180°, 270°) 8 points, circle amplitude = 100% (0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°) 8 points, circle amplitude = 122.1% (35.3°, 54.7°, 125.3°, 144.7°, 215.3°, 234.7°, 305.3°, 324.7°) 4 points, circle amplitude = 141.4% (45°, 135°, 225°, 315°)

The overvoltages must be active at least 256 periods of tDIG to set the test comparator bits in the SSC Interface registers. This works as digital spike suppression.
