CAT811LTBI-GT3 Datasheet

PMIC - Supervisors


The CAT811( CAT811LTBI-GT3 ) and CAT812 are microprocessor supervisory circuits that monitor power supplies. The CAT811 and CAT812 are direct replacements for the MAX811 and MAX812 in applications operating over the industrial temperature range; both have a manual reset input. These devices generate a reset signal, which is asserted while the power supply voltage is below a preset threshold level and for at least 140ms after the power supply level has risen above that level. The underlying floating gate technology, AE2(TM) used by Catalyst Semiconductor, makes it possible to offer any custom reset threshold value. Seven industry standard threshold levels are offered to support +5.0V, +3.3V, +3.0V and +2.5V systems. The CAT811 features a RESET push-pull output (active LOW) and the CAT812 features a RESET push-pull output (active HIGH). Fast transients on the power supply are ignored and the output is guaranteed to be in the correct state at Vcc levels as low as 1.0 V. CAT811LTBI-GT3 Features • Reset valid down to VCC = 1.0V • 6µA power supply current • Power supply transient immunity • Available in SOT-143 packages with Sn or NiPdAu Green Lead finishes. CAT811LTBI-GT3 Applications • Computers, Servers, Laptops • Cable modems • Wireless communications • Embedded control systems • White goods • Power meters • Intelligent instruments • PDAs and handheld equipment
