下表提供了负载开关IC数据表中显示的主要电气特性的定义。
特性 |
符号 |
说明 |
---|---|---|
输入电压 |
VIN |
负载开关IC正常工作的输入电压范围 |
静态电流(导通状态) |
IQ |
负载开关IC导通时流过的静态电流量 |
静态电流(关断状态) |
IQ(OFF) |
负载开关IC关断时流过的静态电流量 |
开关漏电流(关断状态) |
ISD(OFF) |
负载开关IC关断时从VOUT引脚流出的漏电流量 |
CONTROL高电平输入电压 |
VIH |
负载开关IC的控制引脚被视为处于逻辑高电平状态时的最小电压 |
CONTROL低电平输入电压 |
VIL |
负载开关IC的控制引脚被视为处于逻辑低电平状态时的最大电压 |
导通电阻 |
RON |
连接在VIN引脚与VOUT引脚之间的MOSFET的漏极和源极之间的导通电阻 |
反向阻断电流 |
IRB |
当VOUT引脚的电压高于VIN引脚的电压时,从VOUT引脚流入负载开关IC的电流量 |
反向阻断电压阈值 |
VRB |
当VOUT > VIN时,反向电流阻断电路触发的VOUT引脚与VIN引脚之间的电压差(VOUT-VIN)。VRB专门用于具有真正反向电流阻断功能的负载开关IC。 |
反向阻断释放电压阈值 |
VRBR |
当VIN在触发后回升至VOUT以上时,会导致反向电流阻断电路被禁用的VOUT引脚与VIN引脚之间的电压差(VOUT-VIN)。VRBR专门用于具有真正反向电流阻断功能的负载开关IC。 |
欠压锁定(UVLO)上升阈值 |
VUVL_RI |
VIN上升时禁用UVLO的阈值电压。当VIN超过VUVL_RI时,负载开关IC导通。 |
欠压锁定(UVLO)下降阈值 |
VUVL_FA |
VIN下降时触发UVLO的阈值电压。当VIN降至VUVL_FA以下时,负载开关IC会被禁用。 |
过压锁定(OVLO)上升阈值 |
VOVL_RI |
当VIN上升时,会触发OVLO的阈值电压。当VIN超过VOVL_RI时,负载开关IC会被禁用。 |
过压锁定(OVLO)下降阈值 |
VOLV_FA |
当VIN下降时,会禁用OVLO的阈值电压。当VIN低于VOLV_FA时,启用负载开关IC。 |
输出放电导通电阻 |
RSD |
连接在负载开关IC的VOUT引脚与GND引脚之间的内部N沟道MOSFET的导通电阻,用于对连接VOUT引脚的外部滤波电容器进行放电。 |
输出限流 |
ICL |
输出电流受过流保护功能限制的电流电平 |
