Overview
The LM2101DSGR is a half-bridge gate driver manufactured by Texas Instruments, housed in an 8-WSON (2x2) package. It supports a supply voltage range of 9 V to 18 V and withstands bus voltages up to 107 V. The device features non-inverting configuration with a single output capable of delivering peak currents of 0.5 A and 0.8 A. It operates within a temperature range of -40°C to +125°C and includes an 8-V under-voltage lockout threshold for reliable switching protection.
Feature Summary
- High voltage tolerance supporting bus potentials up to 107 V
- Integrated 8-V under-voltage lockout for robust operation
- Compact 8-WSON surface-mount packaging
Applications
- Motor drive systems requiring high-side switching
- Industrial power conversion circuits
- Inverter topologies with isolated gate control
Procurement Notes
Verify the specific suffix 'DSGR' confirms the 8-WSON package and tape-and-reel quantity. Ensure the design accommodates the 107 V common-mode rejection requirements. Confirm thermal management strategies align with the small form factor and operating temperature limits specified in the official datasheet.
Selection Notes
Select this component when a compact half-bridge solution is needed for high-voltage applications. The 8-WSON package suits space-constrained designs. Verify that the input logic levels match the driving circuit and that the 18 V maximum supply voltage is sufficient for the intended gate drive requirements.
Part Context
This part belongs to the LM2101 series of half-bridge drivers from Texas Instruments. It provides a specialized interface for controlling high-side switches in environments with significant voltage fluctuations. The series is designed for industrial and automotive applications requiring reliable isolation and fast switching capabilities.
Replacement Considerations
Check for pin-compatible alternatives within the same family, such as the LM2101DR in SOIC-8 packaging, if board layout changes are permissible. Verify electrical specifications match exactly before substitution.
