All-in-one type capable of protecting and monitoring DC power supplies up to 1000V
Protection from overload and short circuits through current-limiting circuit breaker

Linear Technology Korea announced the launch of the LTM9100 µModule® (micromodule), an all-in-one isolated Anyside™ switch controller capable of protecting and monitoring high-voltage DC power supplies up to 1000V.

The LTM9100 integrates all necessary functions including isolated power and digital telemetry into a compact BGA package, reducing design time and board space.



Linear stated that the LTM9100 performs isolated digital measurements of load current, bus voltage, and temperature through an I2C/SMBus interface, and enables power and energy monitoring for the high-voltage bus.

Additionally, because the LTM9100 is isolated, it can be easily configured for high-side, low-side (ground return), and floating applications. Inrush current can be minimized by gently connecting the load, and the power supply is protected from overload and short circuits through a current-limiting circuit breaker.

Furthermore, the LTM9100 provides diverse functions sufficient to control inrush current in hot-swappable cards, AC converters, motor drives, and inductive loads. Undervoltage and overload lockout thresholds are adjustable, ensuring the load is driven only when the input supply is within the valid range. A complete integrated DC/DC converter including a transformer supplies power to the isolated switch control side.
