3.3-Volt Supply Voltage Supervisor Operates on 16 µA

Product Features

• 16 µA Max supply current
• Preset 2.93 V reset threshold
• 1 V RESET output on power-up
• No external pull-up or pull-down resistors required
• Characterized for operation from -40° to 125°C

The TLC7733 is an ultra-low power (16 µA max) supply voltage supervisor designed for 3.3 V battery-powered systems. This new CMOS supervisor features a push-pull output stage that eliminates the external pull-up and pull-down resistors on the outputs, saving both cost and board space.

The TLC7733 offers designers precision control of 3.3 V microprocessor voltage supplies. The TLC7733 also adds battery-saving micropower operation and static memory backup functionality to the supervisor while reducing board space requirements. Typical applications include laptops, PDAs, games, test and measurement equipment and other battery-powered handheld and portable systems.

The TLC7733 has a 2.93 V sense-voltage threshold that is guaranteed to 1.5% typ. To eliminate undefined states during power-up and power-down, the RESET output is guaranteed asserted when the supply voltage reaches 1 V. Reset delay time is programmable and is set by an external timing capacitor.

The device features functionality for controlling static memory chips with battery backup during power failure. The CONTROL pin, when driven by the memory select pin of a microprocessor, programs the RESET output to drive the chip select (CS) of the memory. The TLC77xx is also available in 3 V, 5 V and adjustable versions. The TLC7733 is available in 8-pin SOIC and plastic DIP.
