Maxims family of automotive regulators operates over a very wide input-
voltage range (up to 72V) and tolerates many voltage transients without any
external circuitry. The ICs are fully specified up to +125°C and can dissipate
more power than most competitive solutions. They also integrate various
features such as a reset output, an extra undedicated comparator (PFI/PFO),
a watchdog timer, enable and hold functionality, and a gate driver (GATEP)
that protects against reverse-battery conditions by using a pFET.
Automotive Regulators with Highest Reliability
Over Wide Operating Range
Overvoltage Protectors Prevent Damage
to Downstream Circuitry
Maxims overvoltage protection circuits can protect your circuit from
continuous voltage levels from below -30V to greater than 90V, and even
higher transients. Some devices feature a limiter mode, which allows
continuous system operation even during overvoltage fault conditions.
The MAX16126/MAX16127 family is designed to protect for all ISO 7637
load-dump conditions.
