Frequently Asked Questions
What is the function of the TPS2226ADBRG4 and how many channels does it have?
The TPS2226ADBRG4 is a dual-slot power interface load switch IC with 3 independent channels. It provides power-on reset and break-before-make switching for safe and reliable power control of dual expansion card slots, commonly used in PC card, ExpressCard, and similar hot-plug module interface designs.
What is break-before-make switching and why is it important in the TPS2226ADBRG4?
Break-before-make switching ensures that the existing power connection is fully interrupted before a new connection is established. In the TPS2226ADBRG4, this prevents momentary short circuits or power conflicts when switching between power sources in dual-slot applications, protecting both the host system and inserted expansion cards from damage during hot-plug events.
What package does the TPS2226ADBRG4 use and what is its pin count?
The TPS2226ADBRG4 comes in a 30-pin SSOP (Shrink Small Outline Package) with plastic/epoxy construction. The SSOP30 package provides a compact footprint compared to standard SOP packages, making it suitable for space-constrained PCB designs in notebook computers and embedded systems with dual-slot card interfaces.
Is the TPS2226ADBRG4 RoHS compliant and what does the G4 suffix indicate?
Yes, the TPS2226ADBRG4 is RoHS compliant and the G4 suffix indicates it meets Texas Instruments' green packaging requirements, including lead-free (Pb-free) construction. The device carries the JESD-609 Code e4, confirming it is manufactured without restricted hazardous substances, making it suitable for use in environmentally-compliant modern electronics assemblies.
