Application Information

Shutdown Operation
In order to reduce power consumption while not in use, the PAM8013/PAM8015 contains shutdown circuitry amplifier off when logic low is placed on
the SD pin. By switching the shutdown pin connected to GND, the PAM8013/ PAM8015 supply current draw will be minimized in idle mode.
Under Voltage Lock-out (UVLO)
The PAM8013/PAM8015 incorporates circuitry designed to detect low supply voltage. When the supply voltage drops to 2.0V or below, the
PAM8013/PAM8015 goes into a state of shutdown, and the device comes out of its shutdown state and restore to normal function only when VDD
higher than 2.2V.
Short Circuit Protection (SCP)
The PAM8013/PAM8015 has short circuit protection circuitry on the outputs to prevent the device from damage when output-to-output shorts or
output-to-GND shorts occur. When a short circuit occurs, the device immediately goes into shutdown state. Once the short is removed, the device
will be reactivated.
Over Temperature Protection (OTP)
Thermal protection on the PAM8013/PAM8015 prevents the device from damage when the internal die temperature exceeds 150°C. There is a 15°C
tolerance on this trip point from device to device. Once the die temperature exceeds the set point, the device will enter the shutdown state and the
outputs are disabled. This is not a latched fault. The thermal fault is cleared once the temperature of the die decreased by 40°C. This large
hysteresis will prevent motor boating sound well and the device begins normal operation at this point with no external system interaction.
POP and Click Circuitry
The PAM8013/PAM8015 contains circuitry to minimize turn-on and turn-off transients or “click and pops”, where turn-on refers to either power supply
turn-on or device recover from shutdown mode. When the device is turned on, the amplifiers are internally muted. An internal current source ramps
up the internal reference voltage. The device will remain in mute mode until the reference voltage reach half supply voltage, 1/2 VDD. As soon as the
reference voltage is stable, the device will begin full operation. For the best power-off pop performance, the amplifier should be set in shutdown
mode prior to removing the power supply voltage.
