3 / 33 page ![]() VDD GND VSENSE GND VDD GND VDD GND 1 PA LM26LV www.ti.com SNIS144F – JULY 2007 – REVISED FEBRUARY 2013 Pin Descriptions Pin Name Type Equivalent Circuit Description No. TRIP TEST pin. Active High input. If TRIP TEST = 0 (Default) then: VTEMP = VTS, Temperature Sensor Output Voltage TRIP Digital 1 If TRIP TEST = 1 then: TEST Input OVERTEMP and OVERTEMP outputs are asserted and VTEMP = VTRIP, Temperature Trip Voltage. This pin may be left open if not used. Over Temperature Switch output Active High, Push-Pull Digital 5 OVERTEMP Asserted when the measured temperature exceeds the Trip Point Output Temperature or if TRIP TEST = 1 This pin may be left open if not used. Over Temperature Switch output Active Low, Open-drain (See Determining the Pull-up Resistor Value) Digital 3 OVERTEMP Asserted when the measured temperature exceeds the Trip Point Output Temperature or if TRIP TEST = 1 This pin may be left open if not used. VTEMP Analog Voltage Output If TRIP TEST = 0 then Analog VTEMP = VTS, Temperature Sensor Output Voltage 6 VTEMP Output If TRIP TEST = 1 then VTEMP = VTRIP, Temperature Trip Voltage This pin may be left open if not used. 4 VDD Power Positive Supply Voltage 2 GND Ground Power Supply Ground The best thermal conductivity between the device and the PCB is achieved by soldering the DAP of the package to the thermal pad on the PCB. The DAP Die Attach Pad thermal pad can be a floating node. However, for improved noise immunity the thermal pad should be connected to the circuit GND node, preferably directly to pin 2 (GND) of the device.
