AS2333F - Secondary Side Housekeeping-Chip

Download the AS2333F datasheet PDF. This datasheet also covers the AS2316F variant, as both devices belong to the same secondary side housekeeping-chip family and are provided as variant models within a single manufacturer datasheet.

General Description

The AS23xx is a housekeeping circuit for monitoring the outputs of power supplies.

It directly senses all the output rails without the need for external dividers and detects undervoltage and overvoltage.

Key Features

  • necessary to allow external caps to set the common timing features of PC type power supplies. In addition, negative rails may be sensed without the necessity of a VEE connection, and negative sensing may be disabled without affecting operation of the positive sense section. This IC is available in 16 lead packages. Outputs include a POK (Power OK) and a fault signal. The AS2316F includes sensing for +/- 12 V, +/- 5 V, and 3.3 V. The AS2333F exchanges a Crow-Bar Driver output for the -5 V input.

AS2316F AS2333F Secondary Side Housekeeping Chips DESCRIPTION The AS23xx is a housekeeping circuit for monitoring the outputs of power supplies. It directly senses all the output rails without the need for external dividers and detects undervoltage and overvoltage. It also provides an additional undervoltage comparator which may be configured with any arbitrary hysteresis to sense a divided down representation of the AC bulk voltage. The housekeeping section provides all the features necessary to allow external caps to set the common timing features of PC type power supplies. In addition, negative rails may be sensed without the necessity of a VEE connection, and negative sensing may be disabled without affecting operation of the positive sense section.
