DESCRIPTION:

The SCT61490S device is a power management IC with multi-channels output. The device is designed to support safety microcontroller in
automotive applications.The SCT61490S integrates a pre-boost controller to support wide input voltage from 3V to 40V. The device has multiple
switch mode regulators and low dropout (LDO) voltage regulators to supply microcontroller, sensors, peripheral ICs and communication interfaces.
Each channel output is continuously monitored, any over-voltage/under-voltage fault will be detected and the device will react depending on
severity. All output voltages are pre-programmed, which saves external feedback divider and minimizes system solution. The device also integrates
window watchdog mode and functional watchdog mode.  The dedicated WDI pin allows trigger pulse generated by MCU. Programmable watchdog
window is suitable for a wide variety of applications.The SCT61490S device has protection features such as thermal shutdown, short-circuit
protection and input over-voltage protection. Sleep mode is available to reduce current consumption.With advanced safety mechanism and
abundant safety outputs, the device supports a wide range of applications up to ASIL-D level.The device is available in a QFN-48(7mm*7mm)
Package.
