E Ink display power rail — TPS651851RSLT
The TPS651851RSLT is a Texas Instruments power management IC purpose-built for E Ink® Vizplex™ displays, also listed for OMAP™ processor companion use. It integrates the multiple voltage rails and sequencing that an electrophoretic display panel needs — a single part replaces a handful of discrete regulators and a supervisor. Input supply range is 3V to 6V, covering a 2-cell Li-ion stack or a 5V USB rail with margin. The IC draws 5.5 mA supply current typical, which is the overhead before the display load; the actual panel current adds on top of that figure.
Package and thermal pad — 48-VQFN (6x6)
Housed in a 48-VFQFN exposed-pad package, supplier device package 48-VQFN (6x6). Operating temperature range is -10°C to 85°C, which covers indoor and most outdoor sheltered environments but excludes engine-bay or direct-sun-exposed enclosures.
