ZHCSOP8A March 2022 – September 2023 TPS3760
PRODUCTION DATA
This design requires voltage supervision on a 12 V power supply voltage rail with possibility of the 12 V rail rising up as high as 42 V. The undervoltage fault occurs when the power supply voltage drops below 7.7 V.
| PARAMETER | DESIGN REQUIREMENT | DESIGN RESULT |
|---|---|---|
| Power Rail Voltage Supervision | Monitor 12-V power supply for undervoltage condition, trigger a undervoltage fault at 7.7 V. | TPS3760 provides voltage monitoring with 1.5% max accuracy with adjustable/non-adjustable variations. |
| Maximum Input Power | Operate with power supply input up to 42 V. | The TPS3760 can support a VDD of up to 65 V. |
| Output logic voltage | Open-Drain Output Topology | An open-drain output is recommended to provide the correct reset signal, but a push-pull can also be used. |
| Maximum system current consumption | 2 μA max when power supply is at 12 V typical | TPS3760 allows for IQ to remain low with support of up to 65 V. This allows for no external resistor divider to be required. |
| Voltage Monitor Accuracy | Maximum voltage monitor accuracy of 1.5%. | The TPS3760 has 1.5% maximum voltage monitor accuracy. |
| Delay when returning from fault condition | RESET delay of at least 12.8 ms when returning from a undervoltage fault. | CCTR = 10 nF sets 12.8 ms delay |
