General Description
The CBM803X/CBMM809X/CBM810X supervisory circuits monitor the power supply voltage in
microprocessor systems. They provide a reset output during power-up, power-down, and
brownout conditions. On power-up, an internal timer holds reset asserted for 240 ms. This holds
the microprocessor in a reset state until conditions have stabilized. The reset output remains
operational with VCC as low as 1 V. The CBM803X and CBM809X provide an active low reset

signal ( RESET ), whereas the CBM810X provides an active high signal (RESET) output. The
CBM809X and CBM810X have push-pull outputs, whereas the CBM803X has an open-drain
output, which requires an external pull-up resistor.
Seven reset threshold voltage options are available, suitable for monitoring a variety of supply
voltages (see Table 3).
The reset comparator features built-in glitch immunity, making it immune to fast transients on
VCC.
The CBM803X/CBM809X/CBM810X consume only 17 μA, making them suitable for low power,
portable equipment. The CBM803X is available in a 3-lead SC70; the CBM809X/CBM810X are
available in 3-lead SOT-23 and 3-lead SC70 packages.
