MIC809-5 - Microprocessor Reset Circuit

Description

The MIC809-5 is a power supply supervisor that provides under-voltage monitoring and power-on reset generation in an industry standard 3-pin SOT package and SC-70 package.

The reset output is asserted at power-on and any time the input voltage drops below the programmed threshold.

Features

  • Under-voltage monitor Power-on reset generation (30ms minimum) Choice of threshold voltages Active-low reset output No external components required Rejects brief input transients Industry standard package and pinout 3-pin IttyBitty™ SOT23-3 package and SC-70 package PDAs, hand-held PCs Embedded controllers Telecommunications systems Power supplies Wireless/c.

MIC809-5 www.DataSheet4U.com Micrel MIC809-5 Microprocessor Reset Circuit General Description The MIC809-5 is a power supply supervisor that provides under-voltage monitoring and power-on reset generation in an industry standard 3-pin SOT package and SC-70 package. The reset output is asserted at power-on and any time the input voltage drops below the programmed threshold. It remains asserted for 30ms (min.) after the input subsequently rises back above the threshold boundary. The MIC809-5 has an active-low reset output. The MIC809-5 is inherently immune to brief power supply transients. Typical supply current is a low 5µA. For those applications that require a manual reset function, see the MIC811/812. For those applications that require a longer reset timeout, see the MIC809/810.
