MTQ1461 is a multi-function System Basis Chip (SBC) sensor designed for CAN automotive applications as main supply for the microcontroller and as interface for a CAN bus network. The chip is capable of withstanding the severe conditions of automotive applications. 

MTQ1461 incorporates a variety of functional blocks to support these applications, such as two 5V low-dropout voltage regulators (LDO), a HS-CAN transceiver, a high-voltage GPIO with embedded protective functions and a 16-bit Serial Peripheral Interface (SPI), a configurable timeout/window watchdog circuit, etc. 

For applications connected permanently to the battery, the chip operates in low-power modes to minimize current consumption. A wake-up from the low-power mode is possible via a message on the CAN bus, via the bi-level sensitive monitoring/wake-up input as well as via Cyclic Wake.
