ExpressCard slot power switch — six high-side outputs
The Texas Instruments TPS2236DAP is a dedicated ExpressCard™ power-interface switch, integrating six high-side outputs with a 1:2 input-to-output ratio — meaning two input rails (1.5 V and 3.3 V) feed six switched outputs, three per voltage rail, to power up to three ExpressCard slots from a single controller. Each output is rated for a continuous 1.3 A maximum, with a typical on-resistance of 45 mOhm, keeping conduction losses low in the 3.3 V main power path.
Fault protection and status reporting
Built-in fault protection includes fixed current limiting and over-temperature shutdown, with Power Good and Status Flag outputs that signal the host controller when the output voltage is within regulation or a fault condition exists.
32-pin HTSSOP with exposed pad — thermal and layout notes
The package ships in Tube form; the base product number is TPS2236, and the DAP suffix identifies the HTSSOP variant with exposed pad.
