PAM8904QJER

Overview

The PAM8904QJER is an automotive-grade piezo sounder driver manufactured by Diodes Incorporated. It generates an 18Vpp output from a 3V supply using an integrated programmable charge pump boost converter operating at 1.0MHz. The device supports 1x, 2x, and 3x voltage modes via CPM pins and accepts input signals between 20Hz and 300kHz. Key electrical parameters include a supply voltage range of 2.3V to 5.0V, a maximum shutdown current of 1µA, and thermal shutdown protection at +150°C. It is housed in a 16-pin U-QFN3030-16 (Type B) package.

Feature Summary

Integrated boost converter generating 9V for 18Vpp piezo drive
Programmable charge pump modes: 1x, 2x, and 3x VDD
Automatic standby control with low current consumption
Overtemperature and short-circuit protection

Applications

Automotive alarms
Dashboard audio systems
GPS navigation units
Electric vehicle approach warning systems
Automotive security devices

Procurement Notes

Verify the AEC-Q100 Grade 2 qualification status and PPAP capability requirements specific to your manufacturing line. Confirm that the U-QFN3030-16 (Type B) package dimensions align with your PCB footprint design. Ensure compliance with RoHS 3 and halogen-free specifications if required by your regional regulations.

Selection Notes

Select the appropriate charge pump mode based on the target supply voltage; use 1x or 2x mode only when VIN exceeds 4.0V to prevent exceeding the maximum output voltage rating. Consider the capacitive load limits (up to 50nF) and ensure external components support the 1.0MHz oscillating frequency. Evaluate thermal resistance characteristics for high-density layouts.

Part Context

This component belongs to the PAM8904 series of piezo sounder drivers. The 'Q' suffix indicates automotive qualification compliant with AEC-Q100 standards. The 'J' denotes the U-QFN3030-16 (Type B) package, while 'ER' specifies the Tape & Reel shipping format containing 3,000 units per reel.

Replacement Considerations

Consult the PAM8904 datasheet for commercial-grade equivalents. Verify pin compatibility and electrical ratings before substituting non-automotive versions in safety-critical automotive applications.
