UT36PFD103 Image

The UT36PFD103 from CAES is a Smart Power Switch Controller (SPSC) IC that is ideal for power distribution with short circuit protection, SpaceVPX – SpaceUM VS1 (+12 V) power switching, Uninterruptable Power Supplies (UPS), launch-vehicle long power harness splicing, Pyro ARM-FIRE controller, waveguide actuation controller, and thruster applications. It requires an input voltage of 8 - 36 V. This power MOSFET controller consists of a 10-bit ADC, discrete device control interface, discrete telemetry, timing circuit, PMBus interface with redundant SMBus, and multiple voltage/current monitoring and protection circuitries. It includes an optional ideal diode (OR-FET) that facilitates redundant power architectures such as UPS and allows for a flexible power switching control for a wide range of space-related applications.

This space-qualified intelligent controller IC is equipped with an inrush current limiting function at the load side, eFuse protection for current fault detection, forward over-current protection, reverse current protection, line, and load-side voltage monitoring based on 10-bit digital telemetry using a PMBus interface, and short-circuit protection to prevent over-load related damages. This military standard controller is available in a surface-mount package that measures 16.1 x 10.75 mm.
