DESCRIPTION

· The TPK1032 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.

· The series features three open-drain output channels, which can be pulled up to any voltage level equal to or lower than VCC.

· Activation via the EN pin initiates a sequential high output across FLAG 1, FLAG 2, and FLAG 3 after individual delay periods.

· Deactivation via the EN pin results in a sequential low output across the channels following selected delay periods.

· Available in SOT23-6 package with a junction temperature range from -40°C to +125°C.

FEATURES

· Input voltage range from 2.5V to 5.5V.

· Single enable control signal input channel.

· Three power sequence channels with open-drain output.

· Selectable timing and power-down sequence options.

· Supports cascaded device output.

· Low power consumption.

APPLICATIONS

· Video surveillance systems.

· Network equipment and servers.

· Industrial control systems.

· FPGA/ASIC/CPLD power sequence control.

· Power supply sequence control in various electronic devices.
