20 / 32 page  Low-Noise, High-Precision, Programmable Linear Hall-Effect Sensor IC With High-Bandwidth (120 kHz) Analog Output and Integrated Fault Comparator A1365 20 Allegro MicroSystems, LLC 115 Northeast Cutoff Worcester, Massachusetts 01615-0036 U.S.A. 1.508.853.5000; www.allegromicro.com Power-On Reset (POR) and Undervoltage Lockout (UVLO) Operation The descriptions in this section assume: TA = 25°C, no output load (RL, CL), and no significant magnetic field is present. • Power-Up At power-up, as VCC ramps up, the output is in a high-impedance state. When VCC crosses VPORH (location [1] in Figure 11 and [1'] in Figure 12), the POR Release counter starts counting for tPORR. At this point, if VCC exceeds VUVLOH [2'], the output will go to VCC / 2 after tUVLOD [3']. If VCC does not exceed VUVLOH [2], the output will stay in the high-impedance state until VCC reaches VUVLOH [3] and then go to VCC / 2 after tUVLOD [4]. • VCC drops below VCC(min)= 4.5 V If VCC drops below VUVLOL [4', 5], the UVLO Enable Counter starts counting. If VCC is still below VUVLOL when the counter reaches tUVLOE, the UVLO function will be enabled and the ouput will be pulled near GND [6]. If VCC exceeds VUVLOL before the UVLO Enable Counter reaches 64 µs [5'], the output will continue to be VCC/2. • Coming out of UVLO While UVLO is enabled [6], if VCC exceeds VUVLOH [7], UVLO will be disabled after tUVLOD , and the output will be VCC / 2 [8]. • Power-Down As VCC ramps down below VUVLOL [6’, 9], the < t UVLOE t UVLOE t PORR t PORR t UVLOD t UVLOD t UVLOD t UVLOE 1 1’ 2’ 4’ 5’ 6’ 7’ 3’ 2 5.0 V UVLOH V PORH V PORL V UVLOL 2.5 High Impedance High Impedance High Impedance High Impedance Slope = V/ 2 CC Slope = V/ 2 CC GND Time Time Time Time GND V CC V CC V OUT 5.0 2.5 GND GND V OUT 3 5 6 7 11 8 10 9 4 Slope = V/ 2 CC < 64 µs V UVLOH V PORH V PORL V UVLOL Figure 11: POR and UVLO Operation – Slow Rise Time Case Figure 12: POR and UVLO Operation – Fast Rise Time Case |
