DESCRIPTION

· The PS10 is a high-voltage power sequencing controller designed for FPGA, microprocessor, DSP, and industrial/embedded subsystems.

· It integrates four timers, programmable UV/OV supervisors, a programmable POR, and four 90V open-drain outputs, eliminating the need for optocouplers or level shift components.

· It operates directly across high-voltage input rails and supports daisy-chaining for sequencing additional systems.

· Available in a compact 14-Lead SOIC package.

FEATURES

· Sequences four supplies, ICs, or subsystems with independently programmable delays (5.0 to 200ms).

· Operates at ±10 to ±90V and supports tracking with Schottky diodes.

· Includes input supervisors: UV/OV lockout/enable and Power-on-Reset (POR).

· Low power consumption with 0.4mA supply current.

APPLICATIONS

· Power supply sequencing for FPGA, microprocessors, and DSP systems.

· Telecom and networking distributed systems (-48V).

· Cellular and fixed wireless systems (-24V).

· PBX systems (-24V) and storage systems (+48V).

· Industrial/embedded system timing and sequencing.

· High-voltage MEMs and display driver supply sequencing.
