TS12001 nanoSmart® Battery Management Under-Voltage Load Switch POWER PRODUCTS Features Description • • • • • The TS12001 Off-Active™ battery management load switch is used to protect a battery from excessive discharge. It consists of an internally generated threshold voltage (VTHRESH), 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 is above VTHRESH, the load switch is on-active. When the input battery voltage falls to VTHRESH, the load switch is Off-Active™ and the quiescent current draw is approximately 100pA. • • • • • Off-Active™ feature with ultra-low pico-amp current Best-in-class Off-active™ quiescent current of 100pA Ultra-low on-active quiescent current of 70nA Accurate on to Off-active™ voltage threshold Threshold voltage options of 1.2V - 4.2V in 100mV steps (programmed at manufacturing) Supervisory over-current limit shutdown Low Rds(on): 175mΩ typical @ 5V Low drop out disconnect from VBAT to loads Turn-on slew rate controlled 500mV off to on-active hysteresis Summary Applications • • • • • • • • • Wide input voltage range: 1.2V – 5.5V Packaged in a 8pin DFN (2x2) Product is lead-free, Halogen Free, RoHS / WEEE compliant Portable Battery Industrial Medical SmartCard RFID Energy Harvesting Systems Block Diagram V CC V OU T R e g u la te d T h r e s h o ld n PG GN D TS12001 Final Datasheet April 11, 2018 Rev 1.5 www.semtech.com 1 of 11 Semtech Typical Applications Disconnect the Battery Charger Load TS12001 VOUT VCC nPG CBYP GND Note: When the TS12001 is Off-Active™, the battery will continue to charge through the body diode between VOUT and VCC.

The following are guidelines for mounting the exposed pad IC on a Multi-Layer PCB with a ground plane. Solder Pad (Land Pattern) Package Thermal Pad Thermal Via's Package Outline Package and PCB Land Configuration For a Multi-Layer PCB JEDEC standard FR4 PCB Cross-section: (square) Package Solder Pad Component Traces 1.5038 - 1.5748 mm Component Trace (2oz Cu) 2 Plane 4 Plane 1.5748mm 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) Multi-Layer Board (Cross-sectional View) 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, thickness of copper, etc. TS12001 Final Datasheet April 11, 2018 Rev 1.5 www.semtech.com 8 of 11 Semtech Mold compound Die Epoxy Die attach Exposed pad Solder 5% - 10% Cu coverage Single Layer, 2oz Cu Ground Layer, 1oz Cu Signal Layer, 1oz Cu Thermal Vias with Cu plating 90% Cu coverage 20% Cu coverage Bottom Layer, 2oz Cu Note: NOT to Scale The above drawing 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 for the linear regulators may have to be de-rated for ambient temperatures above 85C. The de-rate value will depend on calculated worst case power dissipation and the thermal management implementation in the application. Application Using a Single Layer PCB Use as much Copper Area as possible for heat spread Package Thermal Pad Package Outline Layout recommendations for a Single Layer PCB: utilize as much Copper Area for Power Management. In a single layer board application the thermal pad is attached to a heat spreader (copper areas) by using 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 traces 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.
