The MT6328 is 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 powerup, 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.

Description :

a single-chip electrically tuned FM radio circuit. Its peripheral circuit is simple. The application cost is low. The built-in PLL system with 70kHz IF frequency is selectively implemented by active RC filter. The mute circuit can suppress non-IF signals and too weak IF signals.

1. All functional circuits containing radio from RF input to audio output
2. Silent circuit
3. Built-in automatic frequency control system for mechanical tuning
4. Power polarity protection
5. Working power supply voltage can be as low as 1.8V
6. Automatic search from 88MHz key reset to 108 MHz frequency range
