L6370D STMicroelectronics

L6370 2.5 A high-side driver industrial intelligent power switch Features 2.5 A output current 9.5 V to 35 V supply voltage range Internal current limiting PowerSO-20 Thermal shutdown Open ground protection Internal negative voltage clamping to V - 50 V S Description for fast demagnetization Differential inputs with large common mode The L6370 is a monolithic intelligent power switch range and threshold hysteresis in Multipower-BCD Technology, for driving inductive or resistive loads. An internal clamping Undervoltage lockout with hysteresis diode enables the fast demagnetization of Open load detection inductive loads. Diagnostic for CPU feedback and Two diagnostic outputs extensive use of electrical protections make this device extremely rugged and specially suitable for Output status led driver industrial automation applications. Non dissipative short circuit protection Protection against and surge transient (IEC 61000-4-5) Immunity against burst transient (IEC 61000-4- 4) ESD protection (human body model 2kV) Table 1.
