钰泰 ETA6027S2G SOT-23-6 电池充电管理芯片

　　DESCRIPTION

　　The ETA6027 isa load switch which provides full protection to systems and

　　loads which may encounter large current conditions. ETA6027 offers a

　　70mQ2 crrent-limited switch which Can operate over an input voltage

　　range of 2-6V. The current limit can be externally programmed by d

　　precision resistor, ranges from 75mA to 2.2A. Switch control is by a logic

　　input (EN) capable of iterfacing directly with low voltage control signals.

　　Current is prevented from flowing when the switch is off and the output

　　voltage is higher than the input voltage. ETA6027 also features thermal

　　shutdown protection which shuts off the switch to prevent damage to the

　　part when a continuous over-current condition causes excessive heating.

　　When the switch current reaches the current limit, the parts operate in a

　　constant-current mode to prohibit excessive currents from causing

　　damage. The ETA6027 will not turn off after a current limit fault, but will

　　rather remain in the constant current mode indefinitely. The nFAULT output

　　asserts low during over-current and reverse-voltage conditions.

　　ETA6027 is available in three types of package: SOT23-5, S0T23-6,

　　DFN2x2-6L
