TimerBlox: Oscillators, One Shots,  
PWM, Delay, Power on Reset  
Description  
Demonstration circuit 1562B is an engineering tool to  
The center part of the board can be detached as a stream-  
lined circuit, to combine with a pre-existing circuit. For  
applicationflexibility,aprovisionismadeforbufferingand  
inverting the output of the timer. An optional NC7W04P6X  
SC70 package dual inverter can be added at U2 to provide  
this functionality.  
®
design and evaluate the LTC699X-X family of TimerBlox  
circuits. The center section of the board contains a pre-  
configuredTimerBloxfunction. DC1562Bcomesintwelve  
timing function variations as outlined in Table 1.  
Surrounding the center board is a playground prototyping  
area. The prototyping area has pads for DIP-8, S8, MS8,  
or S6 packages with bread boarding connections to each  
pin and two convenient power buses and ground bus  
surrounding the entire area. This area is for conditioning  
signals to control the timer function and for adding loads  
controlled in time.  
Design files for this circuit board are available at

To understandthesimplicityandflexibilityoftheTimerBlox  
function,downloadtheappropriatedatasheetfromtheLTC  
website, www.linear.com. Each evaluation board comes  
with a TimerBlox part, decoupling cap and a bulk decou-  
pling 10µF tantalum cap. Resistors are also installed that  
configuretheTimerBloxdevicesothattheyarereadytouse  
by simply adding power. Changing the default configura-  
tion of the demo board is a simple matter of determining  
a few new resistor values. Simply select a pair of resistor  
values for the DIV value from the data sheet DIV table,  
The outer prototyping section of the board can be used  
with single or dual supplies as required. When using the  
prototyping area, the outermost trace, which is ground,  
must be connected (hand wired) to the ground on the  
center board section. All input and output holes are sized  
for 65mil turret terminals, or wires can be soldered in the  
holes directly.  
Changing the timer configuration requires changing re-  
sistor values on the center board. The resistor lead holes  
can accept “pressed-in” DIP sockets, or resistors can  
be soldered directly in the holes. Pads for 0805 surface  
mount resistors are also included at each position where  
a leaded resistor could be used. Pads are also included  
for three 25-turn trim pots which can be used to replace  
calculate the value of R  
required, replace the resistor  
SET  
on the board, apply power, and go! Single supply power  
between 2.25V and 5.5V and ground must be supplied  
directly to the center board.
