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
