8 Application Information
The benefits of AS5134 are as follows:
8.1 AS5134 Programming
The AS5134 offers the following user programmable options:
position. This useful feature simplifies the assembly process as the magnet does not need to be mechanically adjusted to the electrical zero
position. It can be assembled in any rotation angle and later matched to the mechanical zero position by zero position programming. The 8,5-bit
user programmable zero position can be applied both temporarily (command WRITE OTP, #31) or permanently (command PROG OTP, #25).
magnetic field range of the AS5134 by setting the sensitivity level. The 2-bit user programmable sensitivity setting can be applied both
temporarily (command WRITE OTP, #31) or permanently (command PROG OTP, #25).
frozen and the power consumption is reduced to typ. 1.5 mA. Start-up from this mode to normal operation can be accomplished within 250µs.
This mode is recommended for applications, where low power, but fast start-up and short reading cycle intervals are required.
8.1.1 OTP Programming Connection
Programming of the AS5134 OTP memory does not require a dedicated programming hardware. The programming can be simply accomplished
over the serial 3-wire interface
OTP, #25), a constant DC voltage of 8.0 – 8.5V (=100mA) must be connected to pin 1 (PROG). For temporary OTP write (“soft write”; command
WRITE OTP, #31), the programming voltage is not required. The capacitors must be as close as possible to the pin, to ensure that a serial
inductance of 50nH is not to be exceeded. The 50nH inductance could translate into a cable length of approximately 5cm.
