PMIC – Voltage Regulators – DC DC Switching Regulators

MAX17242ETPB+T is an advanced on-chip power management integrated circuit (PMIC) device that includes a 3MHz switching regulator, battery charger, LED driver, PMOS power switch, watchdog, EEPROM, I/Os, and more. The device’s switching regulator operates from input voltage ranging from 6.5V to 20V, making it well-suited to bridge the gap between low-voltage systems (e.g., portable applications) and higher-powered systems. The device also has a programmable input current limit of between 0.1A and 2A, which helps in avoiding power-related problems.

The MAX17242ETPB+T PMIC includes a switching regulator that includes a fixed off-time current-mode PWM (pulse-width modulation) controller and an external N-channel MOSFET. The controller operates at a fixed frequency of 3MHz, if the current in the inductor rises above a certain level, the off-time is increased so that the current limit can be maintained. The programmable regulation current of the device can be adjusted from 0.1A to 2A in 20mA increments, allowing for greater control and stability during operation. Furthermore, the device includes an adjustable input current limit, allowing for greater flexibility when selecting input sources.

The battery charger feature of the MAX17242ETPB+T adds convenience and flexibility when it comes to powering portable devices. The device is capable of supporting rechargeable battery voltages ranging from 2.7V to 5.5V and charges the battery with a CC/CV (constant-current/constant-voltage) charging scheme. The battery charger has a wide range of options, including programmable charge current, charge voltage, charge voltage regulation, charge termination (full-voltage), and trickle-charge current.

The LED driver feature of the MAX17242ETPB+T PMIC simplifies the LED driving circuitry and allows for the use of smaller components and board space. The LED driver is capable of driving up to 10 LEDs in either a series, parallel, or combination configuration. The LED driver can operate in either PWM or linear dimming modes, allowing for wide range of dimming options for the end user. Furthermore, the LED driver has a programmable current and voltage limits, allowing for greater control and flexibility.

The PMOS power switch of the MAX17242ETPB+T PMIC provides the user with the ability to switch main supplies, while offering a low RDS (on). The device provides a programmable current limit and the option to enable or disable the power switch through a digital input. The power switch also includes a slew-rate control feature, allowing for the reduction of inrush current for more efficient device operation.

The watchdog timer of the MAX17242ETPB+T PMIC is a built-in safety feature that monitors the system for failures. The watchdog feature requires the host to reset the timer periodically, if the host fails to reset the timer, the watchdog will assert a reset signal, returning the system to a known state, preventing random system failures. The watchdog timer can be programmed with a period anywhere from 2.5s to 8.0s and provides built-in debouncing to prevent false resets.

The EEPROM of the MAX17242ETPB+T PMIC allows the user to store information, including operating parameters, and recall it without the need for an external EEPROM. The EEPROM is also capable of storing security codes that can be used to prevent unauthorized access to the device’s settings. Finally, the integrated I/Os of the device can be configured as general-purpose input/outputs, additional switching regulators, or more EEPROM memory when required.

In summary, the MAX17242ETPB+T is an advanced PMIC device that includes a 3MHz switching regulator, battery charger, LED driver, PMOS power switch, watchdog timer, EEPROM, and I/Os. The device’s features make it suitable for bridging the gap between low-voltage and higher-powered systems, allowing for simple and advanced power management solutions.
