L6376D013TR STMicroelectronics

L6376 0.5 A high-side driver quad intelligent power switch Features Multipower BCD technology 0.5 A four independent outputs PowerSO-20 9.5 to 35 V supply voltage range Internal current limit Description Non-dissipative over-current protection Thermal shutdown This device is a monolithic quad intelligent power switch in multipower BCD technology, for driving Under voltage lockout with hysteresys inductive, capacitive or resistive loads. Diagnostic Diagnostic output for under voltage, over for CPU feedback and extensive use of electrical temperature and over current protections make this device inherently External asynchronous reset input indistructible and suitable for general purpose industrial applications. Presettable delay for overcurrent Diagnostic Table 1.
