• Battery type: CR2032 UL-certified battery • Voltage: 3 V • Minimum capacity: 220 mAh • Minimum discharge rate: N/A mA NOTE: Only insert DURACELL® 2032 Lithium battery type CR2032, or equivalent. 2.3 TPL5010EVM Configuration The evaluation board can work standalone or plugged into the MSP430F5529 LaunchPad. 2.3.1 Setting the Time Interval Period Set the Time interval period by tuning the variable resistance (the trimmer can generate resistances in the range between 1 kΩ and 200 kΩ). To tune the value of the resistance: 1. Connect a DMM between pin 1 of R_SEL and GND. 2. Turn the screw on the top of the trimmer until you reach the desired value. 3. Disconnect the DMM at the end of the operation. Alternatively, set the DRV pulse interval with the fix resistances (R_EXT1 = 500 Ω, R_EXT2 = 0 Ω). If required, replace the resistances with customized ones. See Figure 1 for locations of the resistances REXT1 and REXT2. 5 SNAU173–January 2015 TPL5010 Evaluation Module Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated

for further details on the timing: • Configure the trimmer equal to 5 kΩ to set a time interval of 1 s. • When an RSTn pulse is generated by the TPL5010, the red LED (D2) is turned on. The green LED (D1) is turned on when a WAKE signal is generated by the TPL5010. • If the DONE switch (S2) is pushed, a DONE pulse is sent to the TPL5010. If the DONE pulse is sent within the programmed time interval, at the next cycle the green LED (D1) is turned ON. • When the M_RST switch (S1) is pushed, a manual reset pulse is sent to the TPL5010. For both DONE and M_RST pulses, the width of the pulse is proportional to the pressure time. While the M_RST switch is pressed the red LED turns ON. 3.1 Supply Current Measurement 3.1.1 Supply Current Measurement of the TPL5010 Only First, turn off the EVM (ON/OFF switch to OFF position), then disconnect the EVM from the LaunchPad or microcontroller, in order to not load the digital output pins of the DUT. • Leave the I_SEL jumper open. • Do not leave digital input pins floating; Short the DONE pin (second pin of IO header) to GND (first pin of IO header), turn OFF the Q1 and Q2 MOSFET (as explained in Table 3). • Connect a digital multimeter, configured as the current meter (able to measure nA), between AUX_VDD and pin 1 of I_SEL. • Turn on the EVM (ON/OFF switch to ON position). • Read the current consumption on the DMM.
