Pin#1 is the Vcc of the IC and is internally clamped to 15.4V for safeguarding the IC from high supply voltages. The pinout functions may be understood as follows: The figure above shows the standard circuit configuration of the proposed half bridge IC. All the the pinouts are ESD protected internally for safeguarding the chip against static voltages during packaging and handling.īasic Circuit Configuration of the IC Understanding Pinouts of the Half-Bridge Driver IC IRS2153(1)D.An internal dead time feature ensures perfect separation between the outputs for fail proof operations.The chip also includes a Micropower start-up feature which assures guaranteed initialization even under relatively minimal voltage and current conditions.This feature can be very useful for applications where an automatic current or voltage regulation is crucial. Allows an external shut-down feature to be enforced just by adding an additional transistor stage with the IC (Non-latched shutdown on CT pin (1/6th VCC).Consists of a built-in high side driver network which allows a fail-proof conduction of the high-side mosfet (upper mosfet) with the required essential boot-strapped gate voltage.Consists of an internal built-in oscillator circuit with a 50% fixed duty cycle, while its frequency can be simply determined through two external R/C components (CT, RT programmable oscillator).The chip is designed to withstand and operate with voltages as high as 600V DC (15.4 V Zener clamp on VCC).Main Electrical Specificationsīefore we discuss the potential applications of this chip, let's learn a few of its main features first: Let's learn more about this interesting device. The IC IRS2153(1)D which is fundamentally a half-bridge mosfet driver chip can be actually used for a number of different interesting circuit applications such as boost converters, solar compact inverters, and if two of them are coupled can be even configured as a full bridge mosfet driver circuit.
