Part Number: TPS25940

Function: 18V eFuse with True Reverse Blocking and DevSleep Support for SSD

Package: WQFN 20 Pin Type

Manufacturer: Texas Instruments

Pinouts:

 

Description

The TPS25940 eFuse Power Switch is a compact, feature rich power management device with a full suite of protection functions, including a low power DevSleep™ mode that supports compliance with the SATA™ Device Sleep standard.

The wide operating range allows control of many popular DC bus voltages. Integrated back to back FETs provide bidirectional current control making the device well suited for systems with load side holdup energy that must not drain back to a failed supply bus.

Part Number: W583S80

Function: HIGH FIDELITY Power Speech Synthesizer

Package: 30 Pin Type

Manufacturer: Winbond Electronics

Pinouts:

 

Description

The W583S80 series are fabricated using the Winbond CMOS process. The W583xxx family is a new member of the PowerSpeechsynthesizer series, with voice quality which is even better than before. The W583xxx family has adopted the same architecture as the PowerSpeechsynthesizers while replacing the 4-bit ADPCM algorithm with Winbond′s new high fidelity voice synthesis algorithm to produce better quality voice. W583xxx provides IR function, CPU interface, pad option for Ring or Crystal oscillator and voice output in DAC current or PWM type.

 

Features

1. Programmable speech synthesizer

2. New high fidelity synthesis algorithm

3. Wide operating voltage range: 2.4 – 5.5 Volts

4. Direct drive speaker by PWM output or Built-in 8-bit D/A converter

5. Supports CPU interface operation

6. IR interface for command Transmission and Receiving

7. Symbolic compiler supported
