GS6332-3 pin, low power, P reset circuit
• The GS6333 and GS6332 system supervisory circuits are designed to monitor VCC and provide a reset signal to the host processor in the digital system when necessary. No external components.
• When the processor's supply voltage falls below the reset threshold, the reset output is driven active, less than 40µs (TD1). Active for reset for a period of time (TD2), the rising voltage of VCC above this threshold.
• To prevent chattering, the reset threshold voltage has a built-in hysteresis of 0.4% of Vth.
• The GS6333 has an active-low reset output, while the GS6332 has an active-high reset output. Both devices have push/pull output drivers.
• The reset signal is guaranteed to be valid, VCC = 1.0V.
• Low supply current of 3µA makes these devices ideal for battery powered applications. They are designed to reject false resets caused by fast transients.
• Both devices are available in space-saving SOT-23 packages.
