PAM8904EGPR-T from Diodes Incorporated is an integrated charge-pump piezo sounder driver that produces up to 27 VPP from a low-voltage supply with automatic standby and wake-up.
Specifications were checked against the manufacturer data sheet and current distributor listing.
PAM8904E combines a 1x, 2x or 3x charge pump with a differential piezo driver for compact audible alerts and low-power user interfaces.
Generates 18 VPP from 3 V and up to 27 VPP from 4.5 V without an inductor.
Automatic standby and wake-up, controlled from one GPIO, minimize inactive current.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Piezo sounder driver with selectable charge-pump boost
PWM/DIN input and GPIO mode control
1.5 V to 5.5 V supply; input signal 20 Hz to 300 kHz; load up to 47 nF
12-UFQFN Exposed Pad
