3 Description
The TPS99110-Q1 device is a system-basis chip
(SBC) offering a highly integrated solution for the
typical requirements of transmission and engine
electrical control units (ECU) in the automotive space.
The integrated multi-rail power supply is designed to
power microcontroller units (MCUs) and other circuits
in ECUs. The device is designed to support rugged,
high-temperature conditions and incorporates three
low-dropout (LDO) regulators along with three sensor
supplies. The integrated HS-CAN with bus wakeup
and KLINE/LIN transceivers help reduce the
component count on the board. The TPS99110-Q1
functional architecture features undervoltage and
overvoltage monitoring, current limits, temperature
warning flags, and overtemperature shutdown on all
regulator outputs. Additional features include a
window watchdog and SPI Q&A watchdog for MCU-
monitoring.
The device is available in a 64-pin HTQFP (PAP)
PowerPAD™ integrated circuit package.
