14.1. Output Mode
The MLX90316 output type is defined by the Output Mode parameter.
14.1.1. Analog Output Mode
The Analog Output Mode is a rail-to-rail and ratiometric output with a push-pull output stage configuration
allows the use of a pull-up or pull-down resistor.
14.1.2. PWM Output Mode
If one of the PWM Output modes is selected, the output signal is a digital signal with Pulse Width
Modulation (PWM).
In mode 5, the output stage is an open drain NMOS transistor (low side), to be used with a pull-up resistor
to V
In mode 7, the output stage is a push-pull stage for which Melexis recommends the use of a pull-up
resistor to V
The PWM polarity is selected by the PWMPOL1 parameter:
The PWM frequency is selected by the PWM_Freq parameter.
For instance, in Low Speed Mode, set PWM_Freq = 7000 (decimal) to set the PWM frequency at 500Hz.
14.1.3. Serial Protocol Output Mode
The MLX90316 features a digital Serial Protocol mode. The MLX90316 is considered as a Slave node.
See the dedicated Serial Protocol section for a full description (Section 16).
