8 / 12 page MLX92231-AAA-xxx 3-Wire Hall Effect Switch 390109223101 – REV 2 Page 8 of 12 Sept/14 9 Application Information 9.1 Typical Three-Wire Application Circuit C1 10nF VDD GND OUT RPU 10k VCC VOUT Notes: 1. For proper operation, a 10nF to 100nF bypass capacitor should be placed as close as possible to the VDD and ground pin. 2. The pull-up resistor RPU value should be chosen in to limit the current through the output pin below the maximum allowed continuous current for the device. 3. A capacitor connected to the output is not needed, because the output slope is generated internally. MLX92231 9.2 Automotive and Harsh, Noisy Environments Three-Wire Circuit C1 10nF VDD GND OUT C2 4.7nF RPU 10k VCC VOUT R1 100 Ohms Z1 D1 Notes: 1. For proper operation, a 10nF to 100nF bypass capacitor should be placed as close as possible to the VDD and ground pin. 2. The device could tolerate negative voltage down to -24V, so if negative transients over supply line VPEAK< -30V are expected, usage of the diode D1 is recommended. Otherwise only R1 is sufficient. When selecting the resistor R1, three points are important: - the resistor has to limit IDD/IDDREV to 50mA maximum - the resistor has to withstand the power dissipated in both over voltage conditions (VR1 2/R1) - the resulting device supply voltage VDD has to be higher than VDD min (VDD = VCC – R1.IDD) 3. The device could tolerate positive supply voltage up to +27V (until the maximum power dissipation is not exceeded), so if positive transients over supply line with VPEAK> 32V are expected, usage a zener diode Z1 is recommended. The R1-Z1 network should be sized to limit the voltage over the device below the maximum allowed. MLX92231 |
