2.7-4V 双输入/单输出 MOSFET、0.5A 主要输入/0.1A 辅助输入、工作态低电平启用、商用温度
The and TPS2103 are dual-input, single-output power switches designed to provide uninterrupted output voltage when transitioning between two independent power supplies. Both devices combine one n-channel 250 m MOSFET with a single output. The p-channel MOSFET IN2 is used with auxiliary power supplies that deliver lower current for standby modes. The n-channel MOSFET IN1 is used with a main power supply that delivers higher current required for normal operation. Low on-resistance makes the n-channel the ideal path for higher main supply current when power-supply regulation and system voltage drops are critical. When using the p-channel MOSFET, quiescent current is reduced to 0.75 uA to decrease the demand on the standby power supply. The MOSFETs in the TPS2102 and TPS2103 do not have the parasitic diodes, typically found in discrete MOSFETs, thereby preventing back-flow current when the switch is off.
