The ADP197ACPZN-01-R7 is a power management IC (PMIC) from Analog Devices. As a part of the PMIC family, it falls under the “power distribution switches, load drivers” category. The ADP197ACPZN-01-R7 is designed for applications requiring short circuit-, over-temperature- and over-current protection, as well as fast and efficient power management.

The ADP197ACPZN-01-R7 is a low-side-switch IC with a power switch output. It is suited for load switching in systems where low-side switch control is desired and low-side sourcing of load current is required. The device provides high-temperature operation, wide input voltage range, adjustable current-limit protection, adjustable thermal shutdown protection and fast start up. The operating power range of the ADP197ACPZN-01-R7 ranges from 1.3V to 40V, with a maximum load current of 1.5A. Its on-resistance is 0.5Ω.

The ADP197ACPZN-01-R7 PMIC is designed for quick and robust control of output power and load current. The device begins operating mode upon detection of an output voltage greater than 3.2V, which signals the start of the current limit for the output power. The user can use the external sense resistor to set the over-current protection. The device can output current up to 1.5A, and is adjustable via the on-chip differential amplifier.

The ADP197ACPZN-01-R7 features adjustable thermal shutdown protection. There is an on-chip temperature sensor which measures the junction temperature. If the junction temperature reaches an over-temperature limit, the device can automatically shut down. This ensures robust thermal performance and protection against over-temperature or thermal runaway problems.

Another useful feature of the ADP197ACPZN-01-R7 is the open-load protection. This is triggered when there is no load detected on the output, or the load is above the threshold current limit. The device will then shut off the output and opens the switch in order to ensure no current leakage from the output.

The ADP197ACPZN-01-R7 is designed for portable applications. Its power management architecture is well suited for applications that require wide input voltage, fast start up and adjustable current-limit protection. This IC is reliable and robust and can provide short circuit, over-temperature and over-current protection. With its on-chip differential amplifier, temperature sensor, and over-current and over-temperature protection, the ADP197ACPZN-01-R7 allows a system to accurately predict and limit its power consumption.
