User's Guide SNAU148A – JUNE 2013 – Revised JULY 2013 TPL5100EVM User's Guide 1 Introduction The Texas Instruments TPL5100EVM evaluation module (EVM) allows a designer to configure the delay timers of the TPL5100 and measure its very low current consumption. Moreover the TPL5100EVM is ready to be connected to the Launchpads of MSP430, Stellaris and C2000, in order to test its watchdog, timer cycling and power cycling features. Figure 1.
Setup 2.1 www.ti.com INPUT/OUTPUT CONNECTORS AND JUMPER DESCRIPTION I_SEL selects the current consumption measurement method: Open, current consumption measured with DMM connected between TP1 and VDD test points. 3-2 shorted, current consumption = Voltage drop on R_SH divided by R_SH 1-2 R_SH bypass 5-pin header connector to bring out MOS_DRV, TCAL, DONE, VDD_µC, and GND signals. 4 positions SPDT to set the D0, D1, D2 logic values and the source of PGOOD signal (refer to Table 1) IO S1 Table 1.
Supply Current Measurement www.ti.com • • • • • Remove the jumpers VCC and RST of J3 header of the launchpad Set the desired delay, configuring S1 (from position 2 to 4). Set the POWER GOOD source, configuring S1 (position 1), if you set external source connect the voltage source between the EXT_PGOOD and GND test points; do not turn on this voltage source. Refer to the data sheet regarding the allowable voltage range.
Bill of Materials (BOM) 3.2 INDIRECT MEASUREMENT • • Short pin 2 and 3 of I_SEL. DO NOT LEAVE DIGITAL INPUT PINS FLOATING, for instance: – Short the DONE pin (4th pin of IO header) to GND – Set PGOOD =1 (see Table 1) Connect a Digital Multi Meter, configured as the voltage meter, between TP1 and VDD test points. Read the voltage drop on the R_SH on the DMM. The current consumption is simply the voltage drop on R_SH, divided by 1Mohm. • • • 4 www.ti.com Bill of Materials (BOM) Table 3.
Example of Source Code for MSP430 present in the launchpad www.ti.com P1OUT |= BIT0; __delay_cycles(25000); P1OUT &= ~BIT0; // RED LED ON // delay 25ms // Clear P1.0 RED LED Off //BUTTON P1REN |= P1IE |= P1IES |= P1IFG &= // // // // S2 configuration BIT3; BIT3; BIT3; ~BIT3; Pull-up resistor enabled P1.3 interrupt enabled P1.3 Hi/Lo edge P1.3 IFG cleared // WAKE signal P2IE |= BIT0; P2IES &= ~BIT0; P2IFG &= ~BIT0; // P2.0 interrupt enabled // P2.0 Lo/Hi edge // P2.
Example of Source Code for MSP430 present in the launchpad if (DONE == 1) { DONE = 0; } else { DONE = 1; } P1IFG &= ~BIT3; P1IES |= BIT3; www.ti.com // enabled/disabled and viceverasa DONE signal // P1.3 IFG cleared // P1.
