The normal power off sequence is the power on sequence in reverse. If VDD and VIN are turned on at the same time then it is possible that a voltage glitch will appear on VOUT before VDD achieves 1V which is the VT of the main MOSFET. The size of the glitch is dependent on source and drain capacitance loading and the ramp rate of VDD & VIN. SLG7NT614V Turn ON The VOUT ramp follows a linear path, not an RC limitation provided the ramp is slow enough to not be current limited by load capacitance. SLG7NT614V Current Limiting The SLG7NT614V has two forms of current limiting. Standard Current Limiting Mode Current is measured by mirroring the current through the main MOSFET. The mirrored current is then sent through a resistor creating a voltage V(i) proportional to the MOSFET current. The V(i) is then compared with a Band Gap voltage V(BG). If V(i) exceeds the Band Gap voltage then the voltage V(g) on the gate of the main MOSFET is reduced. The V(g) continues to drop until V(i) < V(BG). This response is a closed loop response and is therefore very fast and current limits in less than a few micro-seconds. There is no difference between peak or constant current limit. Temperature Cutoff However, as the V(g) drops the Rds(ON) of the main MOSFET will increase, thus limiting the current, but also increasing the power dissipation of the IC. The IC is very small and cannot dissipate much power. Therefore, if a current limit condition is sustained the IC will heat up. If the temperature exceeds approximately 120°C, then V(g) will be brought low completely shutting off the main MOSFET. As the die cools the MOSFET will be turned back on at 100°C. If the current limiting condition has not been mitigated then the die will again heat up to 120°C and the process will repeat. Short Circuit Current Limiting Mode When V(VOUT) < 250 mV, which is the case if there is a solder bridge during the manufacturing process or a hard short on the power rail, then the current is limited to approximately 500 mA. This current limit is accomplished in the same manner as the Standard Current Limiting Mode with the exception that the current mirror is 15x greater. Because the current mirror is so much larger, a 15x smaller main MOSFET current is required to generate the same V(i). If V(VOUT) rises above approximately 250 mV, then this mode is automatically switched out. 000-007NT614-101 Page 4 of 10 SLG7NT614V  TTotal_ON vs. CAP @ VDD = 3.3 V SLG7NT614V TTotal_ON: ON (50%) - VOUT (90%) VDD = 3.3 V, TA = 25 °C.
