Texas Instruments Debuts TPL5000 and TPL5100 Programmable System Timers

Texas Instruments (TI) TPL5000 and TPL5100 programmable system timers

Texas Instruments announced the TPL5000 and TPL5100 programmable system timers. The new TI devices reduce system standby power consumption. The TPL5000 with watchdog timer and TPL5100 with MOS driver draw only 30 nA of current. This is a reduction of 90% compared to competitive solutions. The TPL5000 and TPL5100 are available now in 10-pin, 3mm by 5mm VSSOP packages. The suggested retail price is $0.60 in 1,000-unit quantities.

The TPL5000 and TPL5100 replace a microcontroller’s (MCU’s) internal timer. This enables the MCU to remain in low-power sleep mode. As a result, the TI programmable devices help designers to achieve system standby power savings of up to 80% over existing solutions.

TI nano timers are ideal for battery-powered and energy harvesting systems, including smoke alarms, CO alarms, intelligent price tags, occupancy sensors, security cameras, door locks, wireless sensor nodes and data loggers. In these applications, the main system is in sleep mode or power-down mode most of the time, which makes the power consumption of the MCU internal timer significant. By drawing much lower current than an MCU timer, the TPL5000 and TPL5100 greatly reduce power consumption and extend the operating life of these systems.
