Offering ST's like Rohm&# 8217;s for automotive use.<\/p>\n
These are single, dual and quad high side gate drivers in a regular package of 6 x 4.9 x 1.7mm gull wing thermal pads, \u201cwith ST pinout. "Compliance with the schedule automotive industry tested LV124 for deep cold cranking allows it to be used with heavy loads such as engine starters and provides reliable performance even in extreme winter conditions.\u201d<\/p>\n

Inputs are compatible with signals from 3 and 5 V CMOS.<\/p>\n
Single channel VN9004AJ (chart<\/strong>), as an example, it is designed to operate from 4 to 28 V, but can withstand power transients up to 36 V thanks to the internal VIPower M0-9 process, ST said.<\/p>\n Typically the on-state resistance for its single channel is 4.2m\u03a9, allowing it to handle up to a 108A limit. The standby current is 500 nA, which allows you to stay connected to the car battery at all times.<\/p>\n Protection includes: undervoltage shutdown, overvoltage latch, load current limiting, overload blocking by on-chip thermal gradient measurement, output inductive negative transient latching, and mechanisms to combat loss to ground and loss of Vcc.<\/p>\n There is also a configurable overheat or power limit lockout with a dedicated fault reset contact, as well as a circuit using external components to implement battery reverse protection.<\/p>\n &# 8220;Flexible reset management allows the developer to customize error responses,\u201d said ST. "The drivers provide protection against battery reverse charge through self-switching capability, which limits the power dissipated on the PCB to an acceptable level."<\/p>\n The response is multiplexed onto the pin to notify the host controller. This includes: current proportional to load current, and indication of: overload, short to ground, thermal shutdown, open load in off state (requires external pull-up) and output shorted to Vcc.<\/p>\n There's a lot going on with these chips - refer to the datasheets for details.<\/p>\n As an example, and his <\/p>\n
