Low frequency clock supports long duration power-on reset
Linear Technology's new low frequency clock, the LTC6995, is configurable for long duration power-on reset and watchdog timer applications.
Part of the company's TimerBlox family, the device offers a wide resistor settable frequency range to provide a clock period from 1ms to 9.5hours.
Upon power on or a reset signal, the LTC6995 will initiate a full output clock cycle. The reset capability and programmable period are specifically intended for long duration timing events.
The LTC6995 is simply programmed, using one to three resistors, with a maximum frequency error guaranteed less than 1.5%. The reset function is designed to truncate the output pulse, clear the internal dividers and hold the output in a high or low state.
The polarity of the reset input and the output signal can be configured for active low or active high operation.
