PINTYPE(1)DESCRIPTION
NO.NAME
1VSUPHV Supply InDevice supply voltage (connected to battery in series with external reverse-blocking diode)
2END IEnable input
3GNDGNDGround (2)(3)
4LINHV I/OLIN bus single-wire transmitter and receiver
5RXDD ORXD output (open-drain) interface reporting state of LIN bus voltage
6TXDD ITXD input interface to control state of LIN output
7nRSTD OReset output (active low)
8VCCSupply OutOutput voltage from integrated LDO
(1) HV - High Voltage, DI - Digital Input, DO - Digital Output, HV I/O - High Voltage Input/Output
(2) When the thermal pad is present, it must be soldered to ground plane.
(3) If the DDA package is placed onto a D package footprint without the thermal pad soldered down, expect the performance to match the D package and not the DDA package.
