IPS4260LTR

Power Distribution Switches, Load Drivers Overview

The IPS4260LTR is a monolithic high-speed quad low-side intelligent power switch designed by STMicroelectronics. It operates within an 8 V to 50 V supply voltage range and features four independent channels capable of driving capacitive, resistive, or inductive loads. Each channel provides overload protection with programmable current limitation via an external resistor on the I_LIM pin. The device integrates thermal shutdown protection and fast demagnetization capabilities for inductive loads using integrated catch diodes combined with external TVS clamping. Diagnostic features include open-load detection and fault indication through common and per-channel open-drain pins.
