钰泰 ETA6020S2G SOT23-6 电池充电管理芯片

DESCRIPTION
The ETA6020 is a load switch which provides full protection
to systems and loads which may encounter large current
conditions. ETA6020 offers a 95mΩ current-limited switch
which can operate over an input voltage range of 2.5-5.5V.
The current limit can be externally programmed by a
precision resistor, ranges from 75mA to 1.7A. Switch
control is by a logic input (EN) capable of interfacing
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. ETA6020
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 ETA6020 will
not turn off after a current limit fault, but will rather
remain in the constant current mode indefinitely. The n
FAULT output asserts low during over-current and
reverse-voltage conditions.

ETA6020 is housed in a tiny DFN2x2-6L package
