EM Microelectronic V6309

The V6309 and V6319 are microprocessor supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5 V powered or 3 V powered circuits. These circuits perform a single function: they assert a reset signal whenever the VDD supply voltage declines below a preset threshold, keeping it asserted for at least 140 ms after VDD has risen above the reset threshold.

FEATURES

n Precision monitoring of 3 V, 3.3 V and 5 V power supply voltages n Fully specified over the temperature range of -40 to + 125 oC n 140 ms minimum power-on reset pulse width: RESET output for V6309 RESET output for V6319 n 16 µA supply current n Garanteed RESET/RESET valid to VDD = 1 V n Power supply transient immunity n No external components needed n 3-pin SOT-23 package n Fully compatible with MAX809/MAX810 and AMD809/AMD810 Typical Operating Configuration

DESCRIPTION

The only difference between the two devices is that the V6309 has an active-low RESET output (which is guaranteed to be in the correct state for VDD down to 1 V), while the V6319 has an active-high RESET output. The reset comparator is designed to ignore fast transients on VDD. Reset thresholds suitable for operation with a variety of supply voltages are available. Low supply current makes the V6309/V6319 ideal for use in portable equipment. The V6309/V6319 come in a 3-pin SOT-23 package

APPLICATIONS
