11 / 26 page SMB214A/B/C Summit Microelectronics, Inc 2128 2.0 6/20/2008 11 AC OPERATING CHARACTERISTICS (Over recommended operating conditions, unless otherwise noted. All voltages are relative to GND.) Note 4 Symbol Description Conditions Min Typ Max Unit 1.5 12.5 25 tPPTO Programmable power-On sequence timeout period. Programmable power-on sequence position to sequence position delay. 50 ms 1.5 12.5 25 tDPOFF Programmable power-off sequence timeout period. Programmable power-off sequence position to sequence position delay. 50 ms OFF 50 100 tPST Programmable sequence termination period Time between active enable in which corresponding outputs must exceed there programmed under voltage threshold. If exceeded, a force shutdown will be initiated. 200 ms 0 tPGF Programmable glitch filter Period for which fault must persist before fault triggered actions are taken. 8 µs 25 50 100 tRESET Reset timeout period Applicable when HEALTHY pin is used as an nRESET output pin. Programmable time following assertion of last supply before nRESET pin is released high. 200 ms 400 200 100 67 50 33 25 SRREF Programmable slew rate reference Adjustable slew rate factor proportional to output slew rate. 20 V/s Channels 0 to 2 tRL LS Driver output rise time CG=100pF, VBATT=4.2V 4.2 ns tFL LS Driver output fall time CG=100pF, VBATT=4.2V 4.2 ns tRL HS Driver output rise time CG=100pF, VBATT=4.2V 2.9 ns tFL HS Driver output fall time CG=100pF, VBATT=4.2V 2.9 ns High to low transition on HSDRV 30 tDT Driver non-overlap delay Low to high transition on buck HSDRV 60 ns Note 4: Timing specifications are 20% shorter for the SMB214C device and 60% longer for SMB214A. |
