6 / 20 page  MTCH101 DS40001664B-page 6 Preliminary 2012-2013 Microchip Technology Inc. 4.0 POWER MODE The MTCH101 has two power mode options: Normal mode and Low-Power mode. The state of the MTPM pin determines the power mode. 4.1 Normal Mode Option The device will run in Normal mode if the MTPM pin is set high and no proximity or touch is detected. In this mode, after an active scan, sleep time is between 69 and 105 ms, as shown in Figure 4-1. The sleep time depends on the VDD voltage, the lower the voltage, the more time it will be in the Idle state. FIGURE 4-1: NORMAL MODE 4.2 Low-Power Mode Option The device will run in Low-Power mode if the MTPM pin is set low and no proximity or touch is detected. In this mode, after an active scan, sleep time is between 572 and 845 ms, as shown in Figure 4-2. As in Normal mode, the sleep time depends on the VDD voltage, the lower the voltage, the more time it will be in the Idle state. FIGURE 4-2: LOW-POWER MODE Note: If the device makes a proximity or touch detection, it will automatically perform active scans continually. Once the device releases from its proximity-detected state, it will return to the power mode set by the MTPM pin. MTI Active Scan Sleep: 69~105 ms MTI Active Scan Sleep: 572~845 ms |
