DESCRIPTION
The SiP6332/SiP6333 are system supervisor circuits
designed to monitor VCC in digital systems and provide a reset
signal to the host processor when necessary. No external
components are required.
When the processor power supply voltage drops below the
reset threshold, the reset output is driven active, in less than
40 ms (TD1). Reset is maintained active for a time period (TD2),
after the VCC rises above the threshold voltage.
To prevent jitter, the reset threshold voltage has a built-in
hysteresis of 0.4% of VTH.
The SiP6333 has an active-low RESET output, while the
SiP6332 has an active-high reset output. Both devices have
push/pull output drives.
The reset signal is guaranteed valid, down to VCC = 1.0 V.
Low supply cRrent of 3 mA makes these devices well suited for
battery powered applications. They are designed to reject fast
transients from causing false resets.
Both devices are available in a space-saving SOT-23
package.
