No Pins Function VS Positive supply voltage. An internal circuit, monitoring the supply voltage, maintains the IC in off-state until VS reaches 9V or when VS falls under 8.5V. The diagnostic is availlable since VS = 5V. 7 VCP Switch driver supply. To minimize the output drop voltage, a supply of about 10V higher than VS is required. In order to use the built-in charge pump, connect a filter capacitor from pin1 to pin. The suggested value assures a fast transition and a low supply ripple even in worse condition. Using the four channels contemporarily, values less than 68nF have to be avoided. 2, 3, 8, 9 O1, O2, O3, O4 1, 10, 11, 20 GND Ground and power dissipating pins. These pins are connected to the bulk ground of the IC, so are useful for heat dissipation. 12,13, 14, 15 I1, I2, I3, I4 Control inputs. Four independent control signals. The output is held off until the voltage at the corresponding input pin reaches 1.35V and is turned off when the voltage at the pin goes below 1.15V. ON DELAY Programmable ON duration in short circuit. If an output is short circuited to ground or carryng a current exceeding the limit, the output is turned-off and the diagnostic activation are delayed. This procedure allows the driving of hard surge current loads. The delay is programmed connecting a capacitor (50pF to 15nF) versus ground with the internal time constant of 1.28µs/pF. The function can be disabled short circuiting this pin to ground. 17 OFF DELAY Programmable OFF duration in short circuit. After the short circuit or overcurrent detection, the switch is held off before the next attempt to switch on again. The delay is programmed connecting a capacitor (50pF to 15nF) versus ground with the internal time constant of 1.28µs/pF. Short circuiting this pin to ground the OFF delay is 64 times the ON delay. 18 R 19 DIAG 6 16 High side outputs. Four independently controlled outputs with built-in current limitation. Asyncronous reset input. This active low input (with hysteresis), switch off all the outputs independently from the input signal. By default it is biased low. Diagnostic output. This open drain output reports the IC working condition. The bad condition (as undervoltage, overcurrent, overtemperature) turns the output low. 5 VC Pump oscillator voltage. At this pin is available the built-in circuitry to supply the switch driver at about 10V higher than VS. To use this feature, connect a capacitor across pin 4 and pin 5. The suggested value assures a fast transition and a minimum output drop voltage even in worse condition. Using the four channels contemporarily, values less than 6.8nF have to be avoided. 4 VP Bootstrapped voltage. At this pin is available the 11V oscillation for the charge pump, at a typical frequency of 200kHz. 3/12 L6376 L6376 ELECTRICAL CHARACTERISTICS (Vs = 24V; Tj = -25 to 125°C; unless otherwise specified.)
