MAS6240 - Piezo Driver

General Description

MAS6240 is a piezo driver device that can drive outputs up to 18Vpp from 3V supply.

An internal three-mode charge pump generates boosted supply voltage for piezo driver.

For adjusting the piezo element sound volume, the charge pump can operate in either of a 1x, 2x or 3x mode.

Key Features

  • Thin 0.75 mm QFN 12 package Piezo Driver.
  • Three-Step Volume Adjusting.
  • Both Single Ended and Differential Output.
  • Up to 18Vpp Output from 3V Supply.
  • One Wire Audio & Shutdown Control Charge Pump.
  • Low External Part Count.
  • Solution without Inductors.
  • 1 MHz Switching Frequency.
  • Multi-Mode Charge Pump (1x/2x/3x).

Micro Analog Systems Oy reserves the right to make any changes without notice. • Both Single Ended and Differential Output • Three-Step Volume Adjusting • Up to 18Vpp Output from 3V Supply • One Wire Audio & Shutdown Control • High Efficiency • Solution without Inductors • Low External Part Count Control logic is switching the charge pump on at first rising signal of digital input (DIN) pin. The switch-off signal will be generated while the signal at DIN has been low at least for 10ms. The piezo driver is enabled at a second rising edge of a pulse at DIN and the signal is transferred to piezo output VO1.
