一,产品概述(General Description)
The JTM9110 is a compact, high-efficiency, synchronous step-up converter with power MOSFETs integrated for a single-cell Li-ion/polymer battery. This converter
consumes only 100uA quiescent current when no switching. When current load is light, this converter enters burst mode to obtain high efficiency. When current load is
heavy enough, it enters fixed-frequency PWM mode. It adopts peak current mode for fast transient response with internal compensation. This converter contains cycle-by-cycle current limiting and short protection circuit. It is suitable for iPad-like computers, smart phones and portable handheld devices. The device is packed in ESOP8 package.

引脚	名字	功能
1	RO	接收输出端: A 端电压比 B 端高 0V 时 RO 为高，A 端电压比 B 端低 300mV 时 RO 为低
2	RE	接收使能端：低电平有效，RE 为高时，接收输出为高阻
3	DE	发送使能端：高电平有效，DE 为低时，发送输出为高阻。 DE 为高电平时芯片工作在发送状态，DE 为低电平且 RE 为低电平时芯片工作在接收状态。
4	DI	发送数据输入端： DI 为低时，A 输出高电平 B 输出低电平，DI 为高时正好相反。
5	GND	地，电源负端
6	A	正向接收输入端也即正向发送输出端
7	B	反向接收输入端也即反向发送输出端
8	VCC	电源正端
