Fax: 408.855.4999 . www.alsc.com Notice: The information in this document is subject to change without notice October 2003 rev 1.0 4 Pin µP Voltage Supervisor with Manual Reset General Description The ASM811/ASM812 are cost effective low power supervisors designed to monitor voltage levels of 3.0V, 3.3V and 5.0V power supplies in low-power microprocessor (µP), microcontroller (µC) and digital systems. They provide excellent reliability by eliminating external components and adjustments. A reset signal is issued if the power supply voltage drops below a preset reset threshold and is asserted for at least 140ms after the supply has risen above the reset threshold. The ASM811 has an active-low output RESET that is guaranteed to be in the correct state for VCC down to 1.1V. The ASM812 has an active- high RESET output. The reset comparator is designed to ignore fast transients on VCC. A debounced manual reset input allows the user to manually reset the systems to bring them out of locked state. Low power consumption makes the ASM811/ASM812 ideal for use in portable and battery operated equipment. The ASM811/ ASM812 are available in a compact 4-pin SOT-143 package and thus use minimal board space. Six voltage thresholds are available to support 3V to 5V systems: Features • New 4.0V threshold option • 9µA supply current • Monitor 5V, 3.3V and 3V supplies • Manual reset input • 140ms min. reset pulse width • Guaranteed over temperature • Active-low reset valid with 1.1V supply (ASM811) • Small 4-pin SOT-143 package • No external components • Power-supply transient-immune design RESET THRESHOLD Suffix Voltage L4.63 M4.38 J4.00 T3.08 S2.93 R2.63 Applications • Computers and Controllers • Embedded controllers • Portable/Battery operated systems • Intelligent instruments • Wireless communication systems • PDAs and handheld equipment • Automotive systems • Safety Systems Typical Operating Circuit VCC VCC VCC µP RESET Input RESET (RESET) GND GND (RESET) MR |
