The PAM8904E is a piezo sounder driver with integrated charge
pump boost converter. The PAM8904E is capable of driving a
ceramic/piezo sounder with 27VPP from a 4.5V power supply. The
charge pump can operate in either 1x, 2x or 3x mode.

Notes:
4. It is possible to drive VOUT, VO1 and VO2 to 3x VDD. A supply voltage of 4.5V of more should not be used in 3x mode as this will exceed the maximum
output voltage rating.
5. When designed under 3x mode, it should be carefully noted that the VOUT absolute maximum value should not exceed 13.5V.

PAM8904E
Application Information
Charge Pump Mode Setting
The Charge Pump Mode (CPM) pins EN1 and EN2 are used to set the charge pump into mode 1x VDD, 2x VDD, 3x VDD or they can be used to put
the PAM8904E in to a forced low current shutdown mode.

Timing Chart and Device Operation
When one or both of the EN pins are pulled high, the device enters normal operation mode, refer to the above table for the mode selection. Once
the PAM8904E senses a valid signal on the DIN pin, the charge pump will start and provide the desired voltage on the VOUT pin and the output
drive VO1 and VO2 start to function after time tON which is typically between 470µs and 2s depending on the mode chosen. Once the input signal
on DIN is removed, the PAM8904E senses this and waits typically 42ms to ensure the signal has been removed. If there is no further valid signal
within the time period tOFF, the PAM8904E enters into a low current standby mode.

PAM8904E
Application Information (continued)
Output Configuration
The PAM8904E is able to be configured either in a differential or a single ended configuration.
Short-Circuit Protection
The PAM8904E has short circuit protection circuitry on the outputs to prevent damage. Once a short circuit is detected on the outputs, the chip will
limit the total current to protect the output device. This is not a latched fault; once the short is removed, the normal operation is restored.
Thermal Protection
If the junction temperature of the PAM8904E exceeds +150°C the device will enter overtemperature shutdown. The outputs and the charge pump
will be switched off. Once the junction temperature cools down to its normal operating condition, the IC will re-start automatically.
