Product details
Overview
PAM8906M1010-13 from Diodes Incorporated is a piezoelectric sounder driver IC with integrated 1.8MHz boost converter, delivering 10V output (VOUT), 36VPP differential drive capability across OUTP/OUTN, and self-excitation mode support for smoke/gas alarm systems. It operates from 2.1V–5.5V input, draws ≤1.3mA operating current (no load), and features <1μA shutdown current - enabling ultra-low-power battery-operated audible alerts.
For engineers reviewing the PAM8906M1010-13 datasheet, PAM8906M1010-13 pinout, PAM8906M1010-13 application, or PAM8906M1010-13 equivalent, key selection criteria include its 10V fixed boost output, MSOP-10 package footprint, self-excitation timing behavior (770µs turn-on delay), thermal/overcurrent/UVLO protections, and compatibility with 2-terminal or 3-terminal piezo sounders up to 150nF loading.
Technical Context
The PAM8906M1010-13 integrates a current-mode boost regulator (1.8MHz fixed switching frequency) and a high-speed complementary piezo driver stage with independent high-side (7.5Ω RDS(ON)) and low-side (3Ω RDS(ON)) outputs. Its self-excitation mode uses external RC network (150kΩ + 1nF) on FB pin to sustain oscillation without external PWM - validated only for 10V/12V variants.
Control logic ties DIN pin to both wake-up/shutdown sequencing (100ms timeout → <1μA shutdown) and PWM amplification path. Internal LDO supplies 5V to internal blocks; VCC requires 1μF decoupling. Protection includes OTP (+150°C), cycle-by-cycle OCP (1A limit), UVLO (1.5V), and VOUT over/undervoltage lockout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Boost Output Voltage | Fixed 10V - sets maximum piezo drive amplitude for consistent SPL in alarm applications |
| Output Drive Capability | 36VPP differential (OUTP–OUTN) - enables loud acoustic output from standard 2-terminal piezo elements |
| Operating Supply Range | 2.1V to 5.5V - supports single-cell Li-ion, 2xAA, or 3.3V/5V system rails without external regulation |
| Quiescent Current | ≤1.3mA (no load, 3.0V VIN) - minimizes battery drain during active alert cycles |
| Shutdown Current | <1μA - extends shelf life and standby time in security devices with infrequent alarms |
| Turn-On Delay | 770µs (typ) from DIN high to 90% VOUT - ensures fast audible response in life-safety systems |
| Switching Frequency | 1.8MHz - allows use of compact 1µH inductor and reduces EMI filtering burden |
Pinout & Package
Package: MSOP-10 (3.0mm × 4.9mm, 0.5mm pitch), RoHS-compliant, matte tin-plated leads, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | LDO output | Internal 5V supply rail for control logic; requires 1μF ceramic capacitor for stability |
| 2 GND | Power ground | Primary return path for boost converter, piezo driver, and logic; critical for low-noise layout |
| 3 BOOT | Bootstrap node | Drives high-side MOSFET gate; connects to 0.1μF capacitor between BOOT and SW |
| 4 SW | Boost switch node | Connects to inductor and Schottky diode anode; carries high-frequency switching current |
| 5 VOUT | Boost output | 10V regulated rail; powers piezo driver stage and requires ≥1μF output capacitor |
| 6 OUTN | Negative piezo output | Complementary driver output; forms 36VPP differential swing with OUTP across piezo element |
| 7 OUTP | Positive piezo output | High-side driver output; switches in anti-phase to OUTN for push-pull piezo excitation |
| 8 FB | Feedback input | Enables self-excitation mode (with external RC) for 3-terminal piezos; tied to VOUT for 2-terminal use |
| 9 DIN | Control input | Accepts PWM signal or logic-level wake-up command; triggers boost enable and driver activation |
| 10 VIN | Battery input | Main power supply (2.1–5.5V); requires 1μF + 10μF decoupling near pin |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1.8MHz boost converter | Eliminates need for external DC/DC; enables compact 1µH inductor and low-EMI operation |
| Self-excitation mode (10V/12V only) | Removes requirement for external oscillator or microcontroller PWM in basic alarm circuits |
| Fast 770µs startup time | Meets stringent response requirements for smoke/gas detection where audible alert must activate rapidly |
| Thermal + overcurrent + UVLO protection | Prevents latch-up or damage during piezo short-circuit, overtemperature, or brownout conditions |
| High-impedance shutdown state | Isolates OUTP/OUTN outputs during sleep, preventing unintended piezo vibration or power loss |

Equivalent & Alternatives
The following parts are listed as comparable options for similar piezo sounder driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments DRV8662 | Higher 200VPP output, but requires external boost; no integrated VOUT regulation or self-excitation | Used in high-SPL industrial alarms needing >120dB; lacks battery-optimized shutdown current | Select when higher voltage drive is required and board space permits external boost components |
| Rohm BD7800FJ | Fixed 12V boost, 1.2MHz switching, no self-excitation mode; lower RDS(ON) (2.5Ω/1.8Ω) | Preferred for MCU-controlled systems where timing precision matters more than autonomous operation | Choose for cost-sensitive designs where 12V output suffices and external PWM is always available |
Compared with DRV8662 and BD7800FJ, the PAM8906M1010-13 uniquely combines integrated 10V boost, self-excitation capability, and sub-1μA shutdown - making it optimal for maintenance-free, long-life battery alarms where minimal BOM count and autonomous operation are critical.

FAQ
Can PAM8906M1010-13 drive a three-terminal piezo sounder?
Yes - the PAM8906M1010-13 supports three-terminal piezo sounders in self-excitation mode using the FB pin with an external RC network (150kΩ + 1nF). This configuration is validated only for 10V and 12V versions per the datasheet, and requires connecting the piezo's center tap to FB while OUTP/OUTN drive the outer terminals.
What is the maximum piezo capacitance supported?
The PAM8906M1010-13 supports up to 150nF piezo loading under standard operating conditions (fDIN = 3.2kHz). For loads exceeding 100nF - common in larger smoke alarm piezos - the datasheet recommends adding a 10μF capacitor at the VOUT pin to maintain regulation stability and reduce ripple-induced distortion.
Does this device require an external Schottky diode?
No - the PAM8906M1010-13 operates without an external Schottky diode. However, adding a 20V/1A Schottky between SW and VOUT reduces power dissipation by ~20%, improves efficiency in high-duty-cycle applications, and is recommended for thermally constrained layouts per Diodes' application notes.
How does the auto-wake-up and shutdown sequence work?
When DIN rises above VIH (≥1.5V), the boost converter enables and reaches 10V output in 770µs; then the piezo driver activates. If DIN falls below VIL (≤0.4V) for >100ms, both boost and driver shut down, reducing current to <1μA. DIN must be pulled low for full shutdown - floating is not allowed.
