ZSPM4121
Under-Voltage Load Switch for Smart Battery Management
Brief Description
Features
The ZSPM4121 battery management load switch
can be used to protect a battery from excessive
discharge. It actively monitors the battery voltage
and disconnects the battery from the load if the
battery drops below a set voltage threshold. When
the input battery voltage reaches 500mV above the
set voltage threshold, the load switch turns on and
connects the battery to the load. The 500mV
hysteresis between the Off Mode and the On Mode
prevents intermittent operation.

The voltage threshold (VTHRESH) can be programmed
at manufacturing to a customer-selected set point in
the voltage range of 1.2V to 4.2V in 100mV increments to support a wide range of applications in consumer, medical, portable, and industrial applications.
This device has ultra-low quiescent current, which
makes it ideal for battery-powered applications.
Typical quiescent current is 100pA in the Off Mode
and 70nA in the On Mode.
The ZSPM4121 includes a slew rate control P-channel load switch, over-current protection, and an
open-drain power indicator pin (NPG). The slew-rate
controlled turn-on characteristic prevents inrush
current and voltage droop on the voltage. The overcurrent limit protects the device in case of an
overload, short-circuit, or ground fault event.

Description of Circuit
The ZSPM4121 battery management load switch includes an internally generated threshold voltage, comparator
with hysteresis, slew rate control for the load switch, a P-channel load switch, and an open-drain indicator pin.
When the input battery voltage rises to 500mV above the threshold, the load switch turns on (the On Mode).
When the input battery voltage falls to the threshold voltage or below, the load switch is off (the Off Mode), and
the quiescent current draw on the battery is in the order of 100pA (typical). The ZSPM4121 threshold voltage is
programmed at manufacturing to an option in the range of 1.2V to 4.2V with 100mV steps between options. The
500mV hysteresis between the Off Mode and the On Mode prevents intermittent operation. The ZSPM4121 also
provides over-current protection.

Layout and Soldering Requirements
To maximize the efficiency of this package for applications on a single layer or multi-layer printed circuit board
(PCB), certain guidelines must be followed when laying out this part on the PCB.

Multi-Layer PCB Layout
The following are guidelines for mounting the exposed pad ZSPM4121 on a multi-Layer PCB with ground a plane.
In a multi-layer board application, the thermal vias are the primary method of heat transfer from the package
thermal pad to the internal ground plane. The efficiency of this method depends on several factors, including die
area, number of thermal vias, and thickness of copper, etc.

Figure 6.4 is a representation of how the heat can be conducted away from the die using an exposed pad
package. Each application will have different requirements and limitations, and therefore the user should use
sufficient copper to dissipate the power in the system. The output current rating of the linear regulators might
need to be de-rated for higher ambient temperatures. The de-rated value will depend on the calculated worstcase power dissipation and the thermal management implementation in the application.

Single-Layer PCB Layout
Layout recommendations for a single-layer PCB: Utilize as much copper area for power management as possible.
In a single-layer board application, the thermal pad is attached to a heat spreader (copper areas) by using a low
thermal impedance attachment method (solder paste or thermal conductive epoxy). In both of the methods
mentioned above, it is advisable to use as much copper trace as possible to dissipate the heat.
Important: If the attachment method is NOT implemented correctly, the functionality of the product is NOT
guaranteed. Power dissipation capability will be adversely affected if the device is incorrectly mounted onto the
circuit board.
