1.2Applications
MT6328 is ideal for power management of 2G, 3G and 4G smart phones and other portable systems.
1.3General Descriptions
MT6328 is a power management system chip optimized for 2G/3G/4G handsets and smart phones, containing 5 buck converters and 28 LDOs optimized for specific 2G/3G/4G smart phone subsystems.
LED drivers support up to 2 channels of LEDs with independent control. Flexible control includes register mode, PWM mode and breath mode.
Sophisticated controls are available for power-up, battery charging and the RTC alarm.
MT6328 is optimized for maximum battery life, allowing the RTC circuit to stay alive without a battery for several hours.
汝州市MT6328 adopts SPI interface and 2 SRCLKEN control pins to control buck converters, LDOs, and various drivers; it provides enhanced safety control and protocol for handshaking with BB.
MT6328 is available in a 206-pin VFBGA package. The operating temperature ranges from -25 to +65°C.
