DESCRIPTION

· The TPK1031 series are simple power sequencers designed for multi-channel power supply control.

· They support up to three devices cascaded to manage nine-channel power rails in a system.

· Features three open-drain output channels, each capable of being pulled up to a voltage level equal to or lower than VCC.

· The sequence of outputs is controlled by an external capacitor, with a reverse sequence upon disablement.

· Available in a small MSOP-8 package with a junction temperature range of -40°C to +125°C.

FEATURES

· Input voltage range from 2.7V to 5.5V.

· Single enable control signal input channel.

· Three power sequence channels with open-drain output and adjustable timing controlled by a capacitor.

· Supports invert output and cascaded device output.

· Low power consumption.

APPLICATIONS

· Video surveillance systems.

· Network equipment and servers.

· Industrial control systems.

· Power sequence control in FPGA/ASIC/CPLD applications.

· Multi-channel power supply sequence control.
