PIN TYPE DESCRIPTION
NO. NAME
1, 14, 19, 24 NC N/A No internal connection.
2 EN1 I Input control for channel 1 activation, internal pulldown.
3 EN2 I Input control for channel 2 activation, internal pulldown.
4 EN3 I Input control for channel 3 activation, internal pulldown.
5 EN4 I Input control for channel 4 activation, internal pulldown.
6 SEL1 I SNS channel-selection high bit; internal pulldown.
7 SEL0 I SNS channel-selection low bit; internal pulldown.
8 DIAG_EN I Enable-disable pin for diagnostics, internal pulldown.
9 FLT O Open drain global fault output. Referred to FAULT, FLT, or fault pin. Recommended 5-10kΩ pullup resistor.
10 LPM O Open drain LPM status pin. Pulled high by external supply if the device is in LPM or SLEEP state. Pulled low internally when device is in ACTIVE mode. Recommended 5-10kΩ pullup resistor.
