12. Self-diagnostic

MLX91216 provides several self-diagnostic features, which prevent the IC from providing erroneous output signal in case of

internal or external failure modes.

Error

Effect on Output

Remarks

Calibration data CRC Error

DIAG_LEVEL=0  active pull-down to GND

DIAG_LEVEL=1  active pull-up to VDD

At power up and in normal mode

Power-On Delay

Pull-down to GND

1ms max followed by settling

Over-voltage Mode 1

Active pull-down to GND

Over-voltage Mode 2

DIAG_LEVEL=0  active pull-down to GND

DIAG_LEVEL=1  active pull-up to VDD

Under-voltage Mode

DIAG_LEVEL=0  active pull-down to GND

DIAG_LEVEL=1  active pull-up to VDD

Valid with enabled ratiometry

(Default: RATIOEN = 1)

Broken OUT

Active pull-down to GND

Broken GND

Output pulled up to VDD

IC is switched off

Broken VDD

Output pulled down to GND

IC is switched off
