The TPIC84125TPWPRQ1 from Texas Instruments is a dedicated low-frequency (LF) antenna driver engineered for automotive applications such as passive entry and passive start systems. This device integrates eight programmable half-bridge MOSFET drivers, which can be configured in various bridge arrangements to deliver modulated current to each coil.
Key features include sophisticated failure detection and handling mechanisms, along with antenna diagnostics for short to GND, short to VBAT, and open load conditions via current measurement. The device supports a linear mode output that generates a sine wave voltage controlled by the microcontroller. The output stage is protected against overloads, short circuits, and over-temperature conditions.
With an operating voltage range of 7V to 38V and an operating temperature range of -40°C to 105°C, the TPIC84125TPWPRQ1 is suitable for demanding automotive environments. It utilizes an SPI interface for driver control and diagnosis. The component is housed in a 28-pin HTSSOP package and is designed for surface mount applications.
This IC is ideal for implementing secure and convenient access systems in vehicles, providing reliable control and monitoring of antenna coils.
