SA56616-XX
CMOS system reset with adjustable delay time

2003 Oct 15
GENERAL DESCRIPTION
The SA56616-XX and SA56615-XX CMOS system resets have low
consumption current of typically 1.0
A and high precision detection
voltage within
±2%. The delay time is adjusted by an external
capacitor working in conjunction with the on-chip delay network. The
SA56615-XX and SA56616-XX have different output configurations
to accommodate a wide variety of microprocessors and logic
devices. The SA56615-XX incorporates a low side open-drain
output topology which requires a pull-up resistor to VDD, while the
SA56616-XX incorporates an active push-pull totem pole output
topology comprised of complimentary P-channel and N-channel
FETs.
The resets operate over a wide operating supply voltage range from
0.7 V to 10 V. Reset detection voltages are available at 0.9 V, 1.8 V,
1.9 V, 2.0 V, 2.7 V, 2.8 V, 2.9 V, 3.0 V, 3.1 V, 4.2 V, 4.3 V, 4.4 V,
4.5 V, 4.6 V and 4.7 V. Other thresholds are offered upon request at
100 mV increments from 0.9 V to 6.0 V. The device comes in the
small outline 5-lead package (SOP003).
