11 / 27 page SMB214A/B/C Summit Microelectronics, Inc 2128 2.2 9/17/2010 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 tPPTO Programmable power-On sequence timeout period. Programmable power-on sequence position to sequence position delay. 1.5 ms 12.5 25 50 tDPOFF Programmable power-off sequence timeout period. Programmable power-off sequence position to sequence position delay. 1.5 ms 12.5 25 50 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. OFF ms 50 100 200 tPGF Programmable glitch filter Period for which fault must persist before fault triggered actions are taken. 0 μs 8 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. 25 ms 50 100 200 SRREF Programmable slew rate reference Adjustable slew rate factor proportional to output slew rate. 400 V/s 200 100 67 50 33 25 20 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 tDT Driver non-overlap delay High to low transition on HSDRV 30 ns Low to high transition on buck HSDRV 60 Note 5: Timing specifications are 20% shorter for the SMB214C device and 60% longer for SMB214A. |
