L-ASC10-1SG48I

The L-ASC10-1SG48I from Lattice Semiconductor Corporation is an In-System Programmable Hardware Management Expander designed for power, thermal, and control plane management. It offers extensive monitoring capabilities, including ten rail voltage monitoring channels with 0.2% typical accuracy for UV/OV fault detection and a fault detection speed under 100 µs. Additionally, it provides two channels for wide-range current monitoring, capable of high-side measurements up to 12V and detecting current faults in under 1 µs.

This device also features three temperature monitoring channels, one on-chip and two using external diodes, along with four high-side MOSFET drivers and four precision trim and margin channels. It includes nine 5V tolerant general-purpose input/output pins and non-volatile fault logging. The L-ASC10-1SG48I is in-system programmable via I2C and supports background programming.

Designed for system-level support, it operates with a 3.3V nominal supply voltage, with a wide input range of 2.8V to 3.6V. The component is specified for an industrial temperature range of -40°C to 85°C. It comes in a 48-pin QFN package and is RoHS compliant and halogen-free. Applications include telecommunication and networking, industrial, test & measurement, medical systems, servers and storage systems, and high reliability systems.
