MAX15013DASA+ is a Protection IC for Driving Low-Side FET Gate Drivers. This device is designed to provide a reliable power switch control solution for systems where negative inductive load switching occurs. It is designed to reduce the complexity of designing reliable power switching in systems with low-side FET gate drives.

Introduction

The MAX15013DASA+ is an integrated circuit (IC) specifically designed for protecting low-side FET gate drives from excessive inductive loads such as motors, solenoids, relays, or other harsh environments. It typically connects to a PWM controller to provide the required gate drive for an N-Channel MOSFET power switch (see Figure 1). The MAX15013DASA+ provides full protection against negative or positive inductive load switching, which can cause damage to the FET gate driver. This device is available in 2 variations: the MAX15013DASA+Q1 and MAX15013DASA+Q2. Both variations are identical, except that the Q2 variant supports a wider range of gate drive voltage and load current.

Features

• Dual monolithic IC designed to protect low-side FET gate drives
• Supports N Channel MOSFETs
• Low-side gate drive with built in bootstrap diode
• Supports positive and negative switching transients
• Soft start current limiting feature
• Undervoltage lockout (UVLO) to prevent system reset when supply voltage drops
• Operates over a supply voltage range from 6 to 48V
• Integrated clamping circuit for gate drive protection
• Supports over-current protection up to 7A
• Operating temperature range of -40°C to +85°C

Application Fields

The MAX15013DASA+ is a highly integrated solution for protecting low-side FET gate drives. It is designed to provide reliable power switch control in systems where negative inductive load switching occurs. Applications include motor control, lighting, power supplies, automotive, and industrial control systems.

Working Principle

The MAX15013DASA+ contains two monolithic ICs. The first IC is the PWM controller which is responsible for driving the gate of the low-side FET. The other IC is the protection IC which protects the FET gate from hazardous switching transients. The protection IC works by monitoring the PWM output current and the system voltage levels. If the voltage level is too low or the current is too high for a certain period of time, the protection IC will activate to protect the FET from damage.

The MAX15013DASA+ also contains a soft start current limiting feature which limits the overshoot current when the FET is switched on or off. This prevents a large current spike from damaging the ICs. Moreover, the device also contains an undervoltage lockout (UVLO) feature which prevents the system from resetting when the supply voltage drops below a certain level.

Conclusion

In conclusion, the MAX15013DASA+ is a reliable integrated protection IC designed to protect low-side FET gate drives from hazardous switching transients. It is suitable for a variety of applications such as motor control, lighting, power supplies, automotive, and industrial control systems.
