L6370Q 2.5 A single high-side smart power switch Datasheet - production data Applications Programmable logic controller Industrial PC peripheral input/output Numerical control machines Drivers for all loads (resistive, capacitive, inductive load) VFQFPN48 (7 x 7 mm) Description The L6370Q is a monolithic intelligent power switch in BCDmultipower technology to drive Features inductive or resistive loads. An internal clamping Operating voltage range (V ) 9.5 V to 35 V S diode enables the fast demagnetization of inductive loads. Diagnostic for CPU feedback and Up to I = 2.5 A operating current out extensive use of electrical protections make this R : 0.1 DS(on) device extremely rugged and especially suitable Internal current limit for industrial automation applications. Thermal shutdown Table 1.
