SS802X

Overview

SS802X is a special MCU development by Sinhmicro for electronic cigarettes that integrates MIC detection, heating wire resistance detection, and short-circuit protection.

Feature

​​​​◼   Enhanced 8-bit MCU with 8KB Code Flash and 192B Data RAM

​​​​◼   Supports single/dual power supply from adapter and/or battery

​​​​◼ Built-in dual-step adjustable LDOs (VINLDO & BATLDO)  
◼ Integrated protection: undervoltage, overtemperature, etc.  
◼ Ultra-low power: 2μA in sleep mode  
◼ 1A max linear charging management unit  
◼ 1 adjustable-threshold NTC circuit  

◼ 2 software-controlled NMOS with PWM synchronization  
◼ Dual digital + 1 analog comparator  
◼ 11-channel 12-bit ADC (7 external + 4 internal inputs)  

◼ Three 16-bit timers (7 PWM outputs), linkable to Charger/NMOS  
◼ E-cigarette mic detection: wake-on-inhale/exhale via capacitance change  
◼ 13 bidirectional I/Os with comparator-triggered protection levels  
◼ Single-pin half-duplex UART interface
