9.1 Application Schematics
9.2 Recommendation / Comments
A bypass capacitor C1 of 10nF is recommended to ensure supply voltage stability in application. It should be placed
between the VDD and GND pin, as close as possible to the MLX92213.
The MLX92213 provides a direct push-pull output, hence aiming to reduce external component count like output pull-up
resistor or capacitor. The use of the output capacitor C2 connected in parallel to the output is optional. If connected
between OUT and GND in such a push-pull configuration, the current sinked by the charge of the capacitor when the
output switches from “0” to “1” leads to an small increase of the average current consumption of the whole module (IC +
capacitor).
Using small capacitor value C2 (less than 50pF) would avoid having such small increase of the module average current
consumption.
For enhanced power management, the EN (Enable) signal can be driven by an external MCU. It basically allows
controlling the state IC and therefore its current consumption according the application requirements:
For more details on the different mode, please refer to the Principle of Operation section.
For application where standard power management is enough (default “Micropower” mode, Standby unused), the EN pin
should be tied to VDD
