UIC811

UNISONIC TECHNOLOGIES CO., LTD UIC811 MICROPROCESSOR RESET CIRCUITS 3 CMOS IC 3  DESCRIPTION The UTC UIC811 series are resetting circuits which can monitor power supplies especially in microprocessor based systems. In normal operation, the UTC UIC811 series can assert a reset under any of the following situation: the power supply drops below a designated reset threshold level (which is available for 3V or 3.3V or 5V system) or MR is forced low. There is an internal active low RESET output which has already been guaranteed to remain asserted for at 140ms least while VCC rises above the designed threshold level.  FEATURES 2 1 SOT-23 (EIAJ SC-59) 2 1 SOT-23-3 (JEDEC TO-236) 3 4 3 4 2 1 12 SOT-143 SOT-343 * Voltage monitor for 3V or 3.3V or 5V power supplies * Valid RESET remains with VCC as low as 1V * Typical supply current: 5µA * Fixed 140ms minimum reset pulse width * With Manual reset input  ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Pin Assignment 1 234 Packing UIC811L-x-AE2-2-R UIC811G-x-AE2-2-R SOT-23-3 RESET VCC GND - Tape Reel UIC811L-x-AE2-3-R UIC811G-x-AE2-3-R SOT-23-3 GND RESET VCC - Tape Reel UIC811L-x-AE3-2-R UIC811G-x-AE3-2-R SOT-23 RESET VCC GND - Tape Reel UIC811L-x-AE3-3-R UIC811G-x-AE3-3-R SOT-23 GND RESET VCC - Tape Reel UIC811L-x-AD4-R UIC811G-x-AD4-R SOT-143 GND RESET MR VCC Tape Reel UIC811L-x-AL4-R UIC811G-x-AL4-R SOT-343 GND RESET MR VCC Tape Reel Note: Pin Assignment : x: Output Voltage, r...
