10/28/2004 - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced a low-power voltage detection circuit that protects microcontrollers while it extends battery life. Consuming only 1 microamp and operating at 1V (minimum), these devices use less power thereby extending the life of the battery. This low-power consumption, coupled with the small packaging, make the MCP102/103/121/131 system supervisors ideal for portable or space-constrained applications.
Systems often need to take into account noisy environments, unreliable power sources or the voltage decay of the systemís battery. These issues may create a variety of system-level problems, which can be eliminated by the use of a voltage supervisor device. The MCP102/103/121/131 voltage supervisors are designed to output a signal that can be used as a system reset indication. When the system voltage is below the operating range, the system enters into a reset condition. After the voltage recovers into the valid operating range, the voltage supervisor releases the system from reset. This process allows these system supervisors to provide system protection from brown-outs, power loss and decaying power supplies (commonly found in battery applications).
The MCP102/103/121/131 system supervisors are available in 3-pin SOT-23 and 3-pin SC70 packages and are priced at $0.33 USD each in 1,000-unit quantities.
