The MIC5842BV is a power distribution switch, load driver and power management integrated circuit (PMIC) designed for use in flexible, mixed-voltage, power supply systems. It features low on-resistance, fast transient response and low quiescent current. The MIC5842BV integrates a dual 200mA PMOS low-side switch and a single 125mA PMOS high-side switch that can be configured differently, depending on the system requirements. The MIC5842BV is designed to drive small loads, such as LEDs, andcan be used in a variety of applications, including automotive electronics, communications, industrial, instrumentation, and power supplies.

The MIC5842BV is capable of operating from a wide range of input voltages, from 2.9V up to 20V, and can also operate from a single 3.3V supply. It has an open-drain output configuration, allowing it to be used with multiple devices and supply voltages. The MIC5842BV can also be used to drive multiple loads without the need for an external voltage divider. In addition, it is capable of providing internal overload protection and capacitive load protection. The MIC5842BV also provides over-temperature protection, and an output enable function.

The MIC5842BV features a proprietary high-speed, low transient time over-voltage protection (OTP) circuit, which prevents over-voltage transients from damaging the circuit. The OTP circuit protects the device from input voltage transients and is programmable to detection voltages from 10V up to 20V. The MIC5842BV can also be used to manage vehicle power distribution and switching systems in automotive applications.

The MIC5842BV has a high efficiency level-shift operation, with an adjustable low-side output voltage and a wide range of voltage levels for both low-side and high-side outputs. The MIC5842BV can be programmed to provide an adjustable low-side output voltage from 2.5V to 20V. The MIC5842BV also has a variable switching frequency, allowing for the adjustment of the dynamic response time, resulting in improved system performance. The device uses internal MOSFETs for high current switching, making it particularly suitable for high current applications.

The MIC5842BV features an adjustable output current capability, with a maximum current of 200mA per switch and a total current capability of 400mA. The maximum switching frequency of the MIC5842BV is 500kHz, allowing for greater control of dynamic response times. The slew rate control of the MIC5842BV can be adjusted internally, allowing for precise control of the output voltage slew rate, thus eliminating the need for external components. The MIC5842BV is available in the industry-standard 5x6mm TSSOP-20 package.

In summary, the MIC5842BV is a highly versatile PMIC that is ideal for use in applications requiring high current switching, adjustable low-side output voltages, and adjustable switching frequencies. Its innovative OTP circuit, adjustable voltage and current, and fast switching times make it an ideal choice for automotive and other power management applications.
