The LM5101M/NOPB is a monolithic switching regulator gate driver integrated circuit (IC) that assists the operation of power switches in a wide range of applications. This IC is part of Texas Instruments’ family of linear-mode power management integrated circuits (PMICs). It integrates a gate driver built with bootstrap circuitry, an undervoltage lockout circuit, a body-diode-emulation section, a short-circuit current limit, and a slew rate control.The advantages of this IC extend from its built-in high-side bootstrap-gate drive capability, which offers no additional external components, to its low oscillation power dissipation and extremely low on-state resistance threshold. This makes it one of the best ICs for gate-driver applications.The LM5101M/NOPB provides an easy way to control the transition time of a voltage regulator to ensure that no ringing or spikes occur on the output, thereby increasing the reliability of the circuit. It also helps protect against inrush currents that can damage the high-side power transistor of a switching regulator.The LM5101M/NOPB is designed to work with both low-side and high-side MOSFETs and is also suitable for applications with either positive or negative logic gate signals. It provides up to 18A of peak sourcing current and up to 36A of peak sinking current when used with typical system loads.This IC is built with a single-input delay (SID) logic module that is used to create adjustable short-circuit current limit, slew-rate control, and undervoltage lockout thresholds. This allows for enhanced system reliability.The LM5101M/NOPB is ideal for applications such as switching regulators, dc-to-dc inverters, motor drives, and other high-current motor control circuits. It can also be employed in various power applications such as computer systems, servers, printers, as well as other power-supply applications.In summary, the LM5101M/NOPB is a versatile IC that can be used in a wide range of applications and is capable of providing reliable gate-driver power switching. It is available in a range of packages and offers adjustable undervoltage lockout, slew-rate control, and short-circuit-current-limit features. Because it provides a single-input-delay logic module to simplify system designs, it is an excellent choice for gate-driver applications.
