Function

OE_TP_INT

Short

Enables the differential driver or I2C mode (when

TRANSP_EN Bit = 1)

Open

Interrupt output when SUSPEND = 0 (J2) and SUSPEND Bit = 1

SUSPEND

Short

Disables power-down mode when SUSPEND Bit = 1

Open

Enables power-down mode when SUSPEND Bit = 1

SPEED

Short

Enables low-speed mode operation

Open

Enables full-speed mode operation

VIF

Short

Provides power to the VIF pin. Can be used for current

consumption measurement

Open

VIF pin is left floating

VBAT

Short

Provides power to the VBAT pin. Can be used for current

consumption measurement

Open

VBAT pin is left floating

ADR

Short

The lsb of the I2C address is '0'

Open

The lsb of the I2C address is '1'

VBAT, VIF

Short

VBAT = VIF (VCOMMON must be 3.0 V - 3.6 V)

Open

VBAT ≠ VIF (use recommended VBAT and VIF)

VTRM, VBAT

Short

Internal LDO regulator bypassed (usable only when the VBAT

supply voltage is between 3.0 V and 3.6 V)

Open

Internal LDO regulator operational
