KMA200,115 Datasheet KMA200,115 | P1-P3

1. Product profile

1.1 General description

The KMA200 is an angle sensor system. The MagnetoResistive (MR) element and the

mixed signal Integrated Circuit (IC) are integrated in one package. This angle system is

already pre-programmed, offsets are compensated and therefore, ready to use.

Via the Serial Peripheral Interface (SPI) the KMA200 is user programmable. This allows

user specific adjustments of the maximum angle, zero point, clamping level and a 32-bit

identifier. The data is stored permanently in an Electrically Erasable Programmable

Read-Only Memory (EEPROM).

The device can be programmed to work either in analog or digital (SPI) output mode.

Furthermore, different analog output characteristics are possible. The resolution is better

than 0.05.

The implemented online diagnosis supervises the input and output signals as well as the

data processing. Deviations and failures of the angle value are indicated in the output

signal. Overall temperature supervision is implemented.

1.3 Quick reference data

[1] Diagnosis GND and V

lost only possible with a pull-up resistor of 5 k to 6 k.

[2] Diagnosis V

lost only possible with a pull-down resistor of 5 k to 6 k.

[3] Load resistor required to enable the diagnosis features. Infinite resistor load permitted for normal operation without the diagnosis

features.

2. Pinning information

[1] The other pins and lead frame parts must not be electrical connected. For operation of the device the

external pins must/have to be used.
