ZHCSM06C december 2020 – may 2023 TPS272C45
PRODUCTION DATA
| Device | Integrated Low Voltage Regulator | Integrated Clamp for Inductive Loads | Fault Diagnosis | Current Limit | Advantage |
|---|---|---|---|---|---|
| TPS272C45A | No | Yes | Single FLT pin, SNS pin provides per -ch fault | Dual level, inrush period | Lower device power dissipation with most of the quiescent current drawn from the lower voltage supply input – enables reduced total heat dissipation and thus smaller module sizes. Connect a 3.3V DC-DC regulator output to VDD pin. Single fault pin reduces IO count. |
| TPS272C45B | Yes | Yes | Single FLT pin, SNS pin provides per -ch fault | Dual level, inrush period | Lower system costs with a single power supply (cost of a low voltage regulator is avoided). |
| TPS272C45C | Yes | No | Single FLT pin, SNS pin provides per -ch fault | Dual level, inrush period | Enables usage of external TVS Clamp for high inductive loading. The device variant can be used with an external supply on VDD pin or using the internal 3.3-V regulation by GNDing the VDD pin. |
TPS272C45D | Yes | Yes | Dual fault FLT1/FLT2 pins | Single level | Dual FLT pins provides easier fault diagnosis. The device variant can be used with an external supply on VDD pin or using the internal 3.3-V regulation by GNDing the VDD pin. |
