Ultra-low-power programmable timer for battery-duty wake cycles
The Texas Instruments TPL5010DDCR is a programmable timer IC that draws just 35 nA from the supply rail. At that quiescent level, the timer's own consumption sits below the self-discharge rate of a CR2032 coin cell — a remote sensor or IoT edge node that sleeps for months and wakes on a timed interval can run years on the same battery without the timer dominating the sleep budget. The -40°C to 105°C operating range covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive auxiliary modules — the timer keeps running through a 105°C soak that would drift a less stable RC-based watchdog.
Package, lifecycle and compliance — what the markings tell you
The TPL5010DDCR ships in the SOT-23-6 Thin / TSOT-23-6 package, a 6-lead surface-mount footprint roughly 2.9 mm x 1.6 mm. The supplier device package is designated SOT-23-THIN. The laser-etched marking on the top of the package should read the TI logo plus the date-code in the font and format TI uses for TSOT-23-6 parts — any mismatch in the marking font or a sanded/re-lasered surface is a red flag for gray-market stock.
