Overview
The L9857-TR-S is a high-voltage high-side driver manufactured by STMicroelectronics. It operates within a supply voltage range of 10 V to 18 V and delivers a peak output current of 500 mA. The device features a delay time of 100 ns and is housed in an 8-SOIC package with a width of 3.90 mm (0.154 inches). This component is classified under PMIC gate drivers.
Feature Summary
- Configured as a high-side driver for load control applications
- Capable of delivering 500 mA peak output current
- Operates with a supply voltage range from 10 V to 18 V
Applications
- Automotive lighting systems
- High-side load switching
- General purpose high-voltage driver circuits
Procurement Notes
Verify the specific suffix -S against the official STMicroelectronics datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the 8-SOIC package dimensions align with your PCB footprint. Confirm that the 10 V to 18 V supply range suits your system's power architecture before finalizing procurement.
Selection Notes
Select this component when a high-side configuration is required with moderate peak current capabilities. The 100 ns delay time should be evaluated against system timing constraints. Ensure the operating environment supports the specified supply voltage limits and that the thermal performance of the 8-SOIC package is adequate for the intended duty cycle.
Part Context
This part belongs to the L98 series of high-side drivers from STMicroelectronics, designed for automotive and industrial applications. It serves as a gate driver for external MOSFETs or direct load driving in high-voltage environments. The series typically offers robust protection features suitable for harsh operating conditions.
Replacement Considerations
Check for L9857-TR or L9857-TR-LF as potential variants. Verify if the -S suffix indicates a specific tape-and-reel or lead-free specification that differs from standard versions. Cross-reference pinouts and electrical specs with official substitution guides.
