TPIC84125TPWPRQ1 General Description

The low-frequency (LF) antenna driver is dedicated to automotive applications requiring passive entry or passive start operational control. It allows for up to eight dedicated drivers, consisting of MOSFET transistors.The device also incorporates sophisticated diagnosis, protection and monitoring features.

Key Features

Output Stage Consists of Eight Programmable Half-Bridge MOSFET Drivers (Configurable in Half, Full, or Parallel Bridges) Which Deliver Modulated Current to Each Coil
Linear Mode Output: Generates a Sine Wave Voltage That is Controlled by the Microcontroller
Output Stage is Overload Protected for Short and Over Temperature
Driver Control and Diagnosis Blocks Drive the Gates of the MOSFETS Via Data From the SPI
Antenna Diagnostics: Short to GND, Short to VBAT, And Open Load Via Current Measurement
Divider Block Generates an Internal Frequency From the Input Clock (Main Controller); Used for the Internal Logic
Sophisticated Failure Detection and Handling
HTSSOP (PWP) 28-Pin Package
Operating Temperature Range: –40°C to +105°C
APPLICATIONS
- Automotive Passive Start and Passive Entry Applications
