The higher its threshold is, the longer this timing. Note 2: This voltage depends on the characteristics of the external N-Channel MOSFET. V GS(th) = 3V for an IRF530. *IRF530 is a registered trademark of International Rectifier. Timing Control – Test Conditions: C =100µF, C RAMP=10nF, VUV = VEE+1.9V, VOV= VEE+0.5V, External MOSFET is IRF530* IRAMP Ramp Pin Output Current 10 µAVSENSE = 0V tPOR Time from UV to Gate Turn On 2.0 ms (Note 1) tRISE Time from Gate Turn On to VSENSE Limit 400 µs tLIMIT Duration of Current Limit Mode 5.0 ms tPWRGD Time from Current Limit to PWRGD 5.0 ms VRAMP Voltage on Ramp Pin in Current Limit Mode 3.6 V (Note 2) |
