MIC4427YN Information

Description

Here's a concise introduction to the MIC4427YN: The MIC4427YN is a dual low-side MOSFET driver from Microchip, designed for high-speed and high-current applications. This 8-pin PDIP packaged device offers a peak output current of 1.5A, a wide input voltage range of 4.5V to 18V, and fast rise/fall times. Key features include under-voltage lockout protection, thermal shutdown protection, and delay time control to prevent shoot-through currents. The MIC4427YN is ideal for applications that demand high efficiency, fast switching speeds, and space conservation, such as motor control systems, power supplies, and switch-mode power converters. With its compact package size and high output current capability, this driver is well-suited for use in a variety of demanding electronic systems where reliability and performance are crucial.

Features

MIC4427YN FAQs

1.Q: What is the propagation delay of the 4427 driver?

A: The maximum propagation delay is 50ns, with typical input/output delays of 17ns and 23ns, respectively.

2.Q: What is the package type and mounting style of the 4427?

A: It comes in an 8-pin PDIP (plastic DIP) package with through-hole mounting. Dimensions: 6.35mm (W) × 9.53mm (L) × 3.81mm (H).

3.Q: Does the 4427 comply with automotive or RoHS standards?

A: The 4427 is RoHS phthalate-compliant but not automotive-qualified (no PPAP/AEC-Q certification).

4.Q: What is the output resistance of the 4427 driver?

A: The output resistance is typically 6Ω (8Ω max), ensuring efficient switching of external MOSFETs.

5.Q: What are the recommended operating conditions for the 4427?

A: Operate at 4.5V–18V supply voltage, -40°C to +85°C temperature range, with CMOS/TTL-compatible input logic levels (1.1V low/1.4V high typical thresholds).

6.Q: What is the absolute maximum supply voltage for the 4427?

A: The absolute maximum supply voltage is 18V. Exceeding this may damage the device.

7.Q: What are typical applications for the 4427 driver IC?

A: It is commonly used in motor control, solenoid drivers, relay switching, and power MOSFET/IGBT gate driving in industrial and automotive systems.

8.Q: What are the key features of the 4427 MOSFET driver?

A: Key features include 1.5A peak output current, 4.5V–18V supply range, 8Ω output resistance, 17ns/23ns input/output delays, CMOS/TTL compatibility, and latch-up proof design.

9.Q: What is the pinout configuration of the Microchip Technology 4427 MOSFET driver?

A: The 4427 is an 8-pin DIP device with two independent low-side drivers. Pin functions include VDD (power supply), GND, two input pins (IN1, IN2), and two output pins (OUT1, OUT2). Refer to the datasheet for the exact pinout diagram.
