E_TJUNC_CRIT

1:1

The junction temperature exceeded the TJUNC_CRIT

threshold.

E_TJUNC_WARN

0:0

Junction temperature crossed the TJUNC_WARN threshold.

Only a low-to-high transition triggers the event.

EVENT_B (0x004)

Field

Slice

Description

Reserved

7:5

E_TJUNC_POR

4:4

The junction temperature crossed the TJUNC_POR threshold

and caused an entry to the reset mode. This bit is only reset

upon a transition from the no-power mode to the reset mode.

E_VDDIO_UV

3:3

VDDIO dropped below a threshold. This event causes the I2C

interface to be reset.

E_TIMER

2:2

The safety timer expired.

E_BUCK_ILIM

1:1

The peak output current exceeded the limit BUCK_ILIM.

E_RDY

0:0

DA9155M moved to the disabled mode. The event is not

generated if VDDIO is below the monitoring threshold

(VDDIO_CONF).

M_TIMER

2:2

Mask bit for E_TIMER

M_BUCK_ILIM

1:1

Mask bit for E_BUCK_ILIM

M_RDY

0:0

Mask bit for E_RDY

11.3.3

CONTROL_A (0x007)

Field

Slice

Description

VIN_DROP

7:0

VIN drop threshold.

N=0x0,0x1,...,0xE: VIN_DROP=4.3+(N×0.05) V
