Soft-Start and Undervoltage Lockout The LT1 769 is soft-started by the 0.33aF capacitor on the Vc pin. On start-up, the Vc pin voltage will quickly rise to 0.5V, then ramp at a rate set by the internal 45cd\ pull-up
1 The short circuit load protection is able to save the device providing the instantaneous on-state dissipation is less than the limiting value for POSM, which is always the case when VDS iS less than VDSP maximum. 2 At the appropriate nominal protection supply voltage for each type. Refer to QUICK REFERENCE DATA. 3 The over temperature protection feature requires a minimum on-state drain source voltage for correct operation. The specified minimum ID ensures this condition. 4 During overload condition. Refer also to OVERLOAD PROTECTION LIMITING VALUES and CHARACTERISTICS. 5 The supply voltage below which the overload protection circuits will be reset. 6 The reverse diode of this type is not intended for applications requiring fast reverse recovery.
