Description
Analog Rail-to-Rail
Low Side (NMOS)
Push-Pull
Low Side (NMOS)
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 VDD.
In mode 7, the output stage is a push-pull stage for which Melexis recommends the use of a pull-up
resistor to VDD.
The PWM polarity is selected by the PWMPOL1 parameter:
• PWMPOL1 = 0 for a low level at 100%
• PWMPOL1 = 1 for a high level at 100%
