Introduction

AI Translation

The PM8834 is a flexible, high-frequency dual low-side driver specifically designed to work with high capacitive MOSFETs and IGBTs. Both PM8834 outputs can sink and source 4 A independently. A higher driving current can be obtained by connecting the two PWM outputs in parallel. The PM8834 provides two enable pins which can be used to enable the operation of one or both of the output lines. The PM8834 works with a CMOS/TTL-compatible PWM signal. The device is available in an SO8 or an MSOP8 package with an exposed pad. The PM8834 is a dual low-side driver suitable for charging and discharging large capacitive loads like MOSFETs or IGBTs used in power supplies and DC-DC modules. The PM8834 can sink and source 4 A on both low-side driver branches but a higher driving current can be obtained by paralleling its outputs. For enhanced control of operations the PM8834 has been designed with dual independent active-high enable pins (ENABLE_1 and ENABLE_2). Connecting these pins to the GND pin will disable the corresponding low-side driver. The PM8834 uses the VCC pin for supply and the GND pin for return. The dual low-side driver has been designed to work with supply voltage in the range of 5 to 18 V. For VCC voltages greater than the UVLO threshold (UVLO_VCC), the PWM input keeps the control of the driver operations, provided that the corresponding enable pin is active. Both PWM_1 and PWM_2 are internally pulled down so, if left floating, the corresponding output pins are discharged. The PM8834, during VCC startup, keeps both low-side MOSFETs in an OFF state until the UVLO threshold is reached. The input pins (PWM_1, PWM_2, ENABLE_1 and ENABLE_2) are CMOS/TTL-compatible and can also operate with voltages up to VCC. The voltage level of the input pins is not allowed to be higher than VCC under any operating condition. The inputs of the PM8834 dual low-side driver are compatible to CMOS/TTL levels with the capability to be pulled up to VCC.
