ZHCSQV1C March 2020 – December 2022 TCAN1463-Q1
PRODUCTION DATA
The TCAN1463-Q1 transceiver is typically used in applications with a host microprocessor or FPGA that includes the data link layer portion of the CAN protocol. These types of applications usually also include power management technology that allows for power to be gated to the application via an enable (EN) or inhibit (INH) pin. A single 5-V regulator can be used to drive both VCC and VIO, or independent 5-V and 3.3-V regulators can be used to drive VCC and VIO separately as shown in Figure 10-1. The bus termination is shown for illustrative purposes.
The TCAN1463-Q1 features an INH_MASK feature. The INH_MASK input pin can be used to disable and enable the INH function as long as the INH is not controlling the power supply to the transceiver or the controller behind the transceiver. This feature can be used to control the power supply to any power-intensive system blocks to avoid powering up the system blocks from low-power mode due to spurious wake-up events which saves power. See Figure 10-2 for an example application schematic.
