U6229B规格书详情
Description
The U6229B is a multifunctional power supply IC which provides four different voltages dedicated to supply components of complex microcontroller systems. Supplied by a battery voltage in the wide range from 6 V to 26 V, the U6229B generates typically 28.4 V with a step-up converter, PWM, external power MOSFET and 150 μH inductivity. This voltage is fed to a step-down converter with external 150 μH inductivity to generate a 7-V auxiliary voltage with a small ripple. By means of this voltage, two linear regulators with only a small power dissipation provide a constant 5-V (±3) supply for microcontrollers and an even more accurate 5-V (±2) supply as a reference for sensors and a/d converters.
Features
● Voltage outputs
– 28.4-V step-up converter with I ≤ 1.2 A
– 7-V step-down converter with I ≤ 400 mA
– 5-V logic supply with I ≤ 14 mA
– 5-V reference voltage with I ≤ 14 mA
● Logic input ENABLE
– Enables the step-up converter
● Analog input VKL15
– Energy-reserve mode switches off the step-up converter at VBatt < 5.25 V
– Controls start-up behavior
● Logic output NRES
– N-reset output with over/ under voltage monitoring of both 5-V supplies
