L6377 is a monolithic Intelligent Power Switch in Multipower BCD Technology for driving inductive, capacitive or resistive loads. It features diagnostic for CPU feedback and extensive use of electrical protections, making it inherently indestructible and suitable for general purpose industrial applications.
The document describes the L6377, a monolithic Intelligent Power Switch in Multipower BCD Technology designed to drive inductive, capacitive, or resistive loads. Key features include externally programmable current limits, non-dissipative over-current protection, thermal shutdown, and under-voltage lockout with hysteresis.
| Output Current | 0.5 A (typical) |
|---|---|
| Supply Voltage Range | 8 to 35 V |
| Operating Temperature (Ambient) | -25 to 85 °C |
| Junction Temperature Range | -25 to 125 °C |
| Short Circuit Output Current Limit Formula | Isc = 5/Rsc |
The output current limit Isc in Amperes is calculated by dividing 5 by the resistance value of the external resistor Rsc in kilo-ohms.
The device shuts off and the DIAG output goes LOW. Normal operation resumes once the chip temperature falls below the hysteresis threshold.
