Device Overview

(1)

For all available packages, see the orderable addendum at the end of the data sheet.

The power-sequence controller uses one-time programmable (OTP) memory to control the power

sequences, as well as default configurations such as output voltage and GPIO configurations. The OTP is

factory-programmed to allow start-up without any software required. Most static settings can be changed

from the default through SPI or I2C to configure the device to meet many different system needs. For

example, voltage-scaling registers are used to support dynamic voltage-scaling requirements of

processors. The OTP also contains a bit-integrity-error detection feature to stop the power-up sequence if

an error is detected, preventing the system from starting in an unknown state.

The TPS65916 device also includes an analog-to-digital converter (ADC) to monitor the system state. The

GPADC includes two external channels to monitor any external voltage, as well as internal channels to

measure supply voltage, output current, and die temperature, allowing the processor to monitor the health

of the system. The device offers a watchdog to monitor for software lockup, and includes protection and

diagnostic mechanisms such as short-circuit protection, thermal monitoring, shutdown, and automatic ADC

conversions to detect if a voltage is below a predefined threshold. The PMIC can notify the processor of

these events through the interrupt handler, allowing the processor to take action in response.
