ZHCSKL3C December 2019 – May 2024 LP8866-Q1
PRODUCTION DATA
The LP8866-Q1 is designed to operate from a car battery. The VIN input must be protected from reverse voltage and voltage dump condition over 48V. The impedance of the input supply rail must be low enough that the input current transient does not cause drop below VIN UVLO level. If the input supply is connected with long wires, additional bulk capacitance may be required in addition to normal input capacitor.
The voltage range for VDD is 3V to 5.5V. A ceramic capacitor must be placed as close as possible to the VDD pin. The boost gate driver is powered from the CPUMP pins. A ceramic capacitor must be placed as close to the CPUMP pins as possible.
