L6370Q 2.5 A single high-side smart power switch Datasheet - production data Two diagnostic outputs Output status LED driver Non-dissipative short-circuit protection Surge and transient protection (IEC61000-4-5) Burst transient immunity (IEC61000-4-4) ESD protection (human body model 2 kV) VFQFPN48 (7 x 7 mm) Applications Features Programmable logic controller Industrial PC peripheral input/output Type V R I V demag DS(on) out s Numerical control machines L6370Q V - 50 V 0.1 2.5 A 50 V s Drivers for all loads (resistive, capacitive, inductive load) 9.5 V to 35 V supply voltage range Description Internal current limit Thermal shutdown The L6370Q is a monolithic intelligent power switch in BCDmultipower technology to drive Open ground protection inductive or resistive loads. An internal clamping Internal negative voltage clamping for fast diode enables the fast demagnetization of demagnetization (V - 50 V) s inductive loads. Diagnostic for CPU feedback and Differential inputs with large common mode extensive use of electrical protections make this range and threshold hysteresis device extremely rugged and especially suitable for industrial automation applications. Undervoltage lockout with hysteresis Open load detection Table 1.
