Brief Description
The ZSPM4121 battery management load switch
can be used to protect a battery from excessive
discharge. It actively switches the battery power
source off if it drops to a set threshold (Off Mode).
When the input battery voltage is above the
threshold, the load switch is on (On Mode). The
ZSPM4121 threshold voltage (V
grammed at manufacturing to a set point in the
range of 1.2V to 4.2V with 100mV steps between
options.
When the input battery voltage has been switched
off by the ZSPM4121, the quiescent current draw on
the battery is in the order of 100pA (typical). The
quiescent current in the on state is as low as 70nA.
The ZSPM4121 consists of an internally generated
threshold voltage, a comparator with hysteresis,
slew rate control for the load switch, a P-channel
load switch, and an open-drain indicator pin. The
500mV hysteresis between the Off Mode and the On
Mode
ZSPM4121 also provides over-current protection.
