General Description
The AME8500 family allows the user to customize the
CPU reset function without any external components.
The user has a large choice of reset voltage thresholds,
reset time intervals, and output driver configurations, all
of which are preset at the factory. Each wafer is trimmed
to the customer's specifications.
These circuits monitor the power supply voltage of
µP
based systems. When the power supply voltage drops
below the voltage threshold a reset is asserted immedi-
ately (within an interval T
D1
). The reset remains asserted
after the supply voltage rises above the voltage threshold
for a time interval, T
D2
. The reset output may be either
active high (RESET) or active low (RESETB). The reset
output may be configured as either push/pull or open
drain. The state of the reset output is guaranteed to be
correct for supply voltages greater than 1V.
The AME8501 includes all the above functionality plus
an overtemperature shutdown function. When the ambi-
ent temperature exceeds 80
o
C a reset is asserted and
remains asserted until the temperature falls below 60
o
C.
Space saving SOT23 packages and micropower qui-
escent current (<3.0µA) make this family a natural for
portable battery powered equipment.

This pin can be ordered as RESET or RESETB. RESET is active high.
RESETB is active low. It is also available with an open drain or pushpull
output.
Positive power supply. A reset is asserted after this voltage drops below
a predetermined level. After V
DD
rises above that level the reset output
remains asserted until the end of the reset timeout period.

求助
你好,各位大大,凯美瑞车分2.0的和2.4的,2.0的仪表和2.4的仪表有一点点区别,2.0的定速巡航灯不会亮,2.4的就会亮,经查是因为2.0的仪表程序中没有点亮巡航灯的程序,是通过can总线控制的,控制IC型号为93C56,不知道这里有没有高手能将这个点亮巡航灯的程序加进去,谢谢各位了.求助这个描述太简单了点。这两个车的参数差别大吗??如果一样直接对COPY一个93C56。要改程序,首先得要了解如果一但改了这东西会不会对其它的东西有影响。谢谢大大的回复,我有试过将2.4的93c56...

MCP1700低静态电流LDO
MCP1700系列是采用CMOS工艺制造的低压差(LDO)稳压器,它可以产生高达250mA的电流,而其静态电流只有1.6μA(典型值)。它的输入电压范围为2.3V至6.0V,因此对于两或三节电池供电的系统和单节锂离子电池供电的系统,MCP1700都是一个理想的选择。在输入输出电压差(VOUT=2.8V)只有178mV的情况下,MCP1700也能产生250mA的电流。MCP1700的输出电压容差在+25°C时的典型值为±0.4%,在最大工作结温范围(-4...
