Data Sheet Rev. 1.01 / February 2013 ZSPM4121 Under-Voltage Load Switch for Smart Battery Management Power Management Power and Precision 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. Threshold voltage options of 1.2V to 4.2V in 100mV steps (factory programmed) Wide input voltage range: 1.2V to 5.5V Supervisory over-current limit shutdown: (3A) Low drop-out disconnect from VCC to loads Controlled turn-on slew rate 500mV Off Mode to On Mode hysteresis Related ZMDI Smart Power Products ZSPM4141 Ultra-Low-Power Linear Regulator Available Support Evaluation Kit Support Documentation Physical Characteristics Package: 8-pin DFN (2mm x 2mm) ZSPM4121 Block Diagram ZSPM4121 Benefits Best-in-class ultra-low quiescent current in Off Mode: 100pA (typical) Ultra-low quiescent current in On Mode: 70nA (typical) Accurate on/off voltage threshold Low Rds(on): 175mΩ (typical) @ 5V VCC VOUT Regulated VTHRESH NPG GND For more information, contact ZMDI via [email protected]. © 2013 Zentrum Mikroelektronik Dresden AG — Rev. 1.01 — February 7, 2013.

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.

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 6.2 Package and PCB Land Configuration for Multi-Layer PCB Solder Pad (Land Pattern) Package Thermal Pad Thermal Vias Package Outline Figure 6.3 JEDEC Standard FR4 Multi-Layer Board – Cross-Sectional View (square) Package Solder Pad 1.5038 - 1.5748 mm Component Trace (2oz Cu) 2 Plane 4 Plane 1.5748mm Component Traces Thermal Via Thermal Isolation Power plane only 1.0142 - 1.0502 mm Ground Plane (1oz Cu) 0.5246 - 0.5606 mm Power Plane (1oz Cu) 0.0 - 0.071 mm Board Base & Bottom Pad Package Solder Pad (bottom trace) 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.
