The TLC7705, a new micropower supply voltage supervisor from Texas Instruments, protects microprocessors from power supply deviations in battery-operated, 5-V systems, such as portable computers and hand-held instrumentation.
Consuming 100 times less power, the TLC7705 is a low power (25 microamps) alternative to the industry standard TL7705.
In the event of an under-voltage condition, the TLC7705 provides the microprocessor with a programmable delayed reset pulse. On power up, the reset is active at 2 V and outputs are defined when supply voltage reaches 1 V.
The device features push-pull outputs so no external pull-up or pull-down resistors are required.
Manufactured using TI's LinBiCMOS process, the TLC7705 is available now from TI and its authorized distributors. t
