TPIC1021A is a LIN transceiver produced by TI company. It supports the LIN 2.0 physical layer specification and supports a communication speed of 20kbps. It has a sleep mode, in which the current consumption is extremely low. It supports LIN slave applications and supports LIN slave wake-up. It has EMI and ESD protection and supports ISO9141 (K-Line)-Like functions.
The TPIC1021A-Q1 is a Local Interconnect Network (LIN) physical interface that integrates a serial transceiver with wake-up and protection features. It is designed for low-speed in-vehicle networks, supporting data rates up to 20 kbps and conforming to LIN Physical Layer Specification Revision 2.0 and SAE J2602.
| LIN Bus Speed | up to 20-kbps |
|---|---|
| Supply Voltage Range | 7 V to 27 V DC |
| ESD Protection | +12 kV (Human-Body Model) |
| LIN Pin Voltage Handling | -40 V to 40 V |
| Internal Pullup Resistor | 830 kΩ |
| Master Application Pullup | 1 kΩ plus series diode |
The device supports LIN bus speeds up to 20 kbps as specified in the LIN specification.
No, slave applications do not require external pullup components because the device has an internal pullup resistor and series diode.
The dominant state timeout timer disables the transmitter to allow the LIN bus to return to the recessive state.
